In v e r t i c a l space a s p e c i a l t r a n s f o r m a t i o n i s needed: v e r t i c a l c o o r d i n a t e s changes l i n e a r l y w h i l e h o r i z o n t a l c o o r d i n a t e s do n o t change. In t h e second c o o r d i n a t e system t h e v e r t i c a l p l a n e i s i n f a c t an u n f o l d e d s u r f a c e t h a t i s s i n g l e c u r v e d i n t h e f i r s t system.

A remarkable b e n e f i t i s t h a t d a t a i n t e r c h a n g e v i a p h y s i c a l f i l e s c a n not d i s t u r b any i n t e r p r e t a t i o n (without s p e c i a l e n t i t i e s f o r t o l e r a n c e s s t i l l t o be developped i n STEP ? ) . T h i s i s s u e may have consequencies on topology, because g e o m e t r i c p o i n t s can then be compared e x a c t l y . Furthermore a new subtype o f curve i s needed: t h e s p i r a l , c u r l i n g inwards, outwards o r upwards. E s p e c i a l l y f o r road d e s i g n a inwards c u r l i n g s p i r a l i s needed: t h e (planar) c l o t h o i d , o f which t h e c u r v a t u r e i s l i n e a r w i t h t h e e v o l v e d l e n g t h . The r e p r e s e n t a t i o n i n c a r t e s i a n c o o r d i n a t e s i s o n l y p o s s i b l e by an a p p r o x i m a t i n g s e r i e s o f terms. Agreements i n d e t a i l a r e n e c e s s a r y about o r i g i n , s i g n c o n v e n t i o n s and a c c u r a c y (and perhaps c u r v a t u r e domain) t o s u p p o r t . In t h e f i e l d o f s u r f a c e m o d e l l i n g a new type o f bounded_surface i s needed: a t r i a n g u l a r _ c o m p o s i t e _ s u r f a c e o f which t h e patches a r e p l a n e t r i a n g l e s . M o s t l y t h i s type o f s u r f a c e has been g e n e r a t e d from a s e t o f p o l y l i n e s ( t h a t do n o t i n t e r s e c t i n h o r i z o n t a l s p a c e ) , w h i l e i t i s i m p o r t a n t t o know which edge o f t h e s u r f a c e comes from a p o l y l i n e and which edge i s g e n e r a t e d i n between. I have no i d e a , y e t , o f t h e impact on t h e r e l a t i o n between geometry and topology. As comment on t h e d r a f t p r o p o s a l o f B i l l Anderson (june 1993) about s w e p t _ s u r f a c e I agree w i t h t h e i d e a o f a c u r v e d p r o f i l e _ p a t h , but I have some remarks. The o r i e n t a t i o n v e c t o r s o f t h e p l a n e o f t h e p r o f i l e curve a r e : - both f i x e d o r - one f i x e d and one p e r p e n d i c u l a r t o t h e p a t h o r - both p e r p e n d i c u l a r t o the path.

data (both numerical control fabrication and installation) can be extracted, enables the preparation of detailed packages containing the graphical data, as well as the associated material and sequencing information, thus assuring the producibility of the design. Figure 1 outlines the history of computer aided design (CAD) at Ingalls. The progression from a basic 2D drafting system, which significantly improved drafting productivity, to a fully integrated 3D C A D / C A M system is evident. The current system improves design and construction producuviry by producing an interference-free design and generating manufacturing data directly from the product model.

S A ' A R 5 CHARACTERISTICS A N D PERFORMANCE The SA'AR 5 corvette is a state-of-the-art combatant designed to meet the requirements of the 90s and beyond. The principal design objective was to maximize combat effectiveness while retaining a high degree of survivability. The principal characteristics of this "pocket cruiser" are listed in Table I. The CODOG propulsion system, consisting of two 3000 HP MTU cruise diesel engines and a 30.000 HP G E LM2500 gas turbine geared to both shafts, enables cruising speeds of 21 knots and a maximum speed in excess of 34 knots. The propulsion plant monitoring and control system, a portion of the ship monitoring and control system, is an electronic based data multiplexing system. The data is routed on a shipwide data bus along with ship control. ^ plant control, and damage control signals. The use of redundant data paths and multifunction consoles ensures system integrity over a wide range of operating scenarios. Five monitoring and control consoles are distributed in the pi ot house and machinery spaces. Four of the five are virtually identical, allowing any monitoring and control functioni to be performed from any console. Sophisticated, yet reliable, system software includes control algorithms which provide maximum system performance and control safeguards. User-friendly menu-driven color displays include pushbutton control functions and pictorial displays of system configuration, such as valve status and operating parameters^ The ship monitoring and control system is representative of the ship s overall design philosophy, which incliides the incorporation of state-of-the-art systems specifically engineered to provide maximum performance and survivability. e

C A D / C A M BENEFITS

A number of benefits have been realized from the use of a three-dimensional C A D / C A M system. Some of these benefits were anticipated when the system was implemented; others have emerged during the course of the design process: -

Superior Interference Checking: This benefit was the primary reason why a three-dimensional system was implemented. It has proven to be a very powerful tool and is much more accurate than manual composite techniques. A three-dimensional CAD system can control modeled objects at all points in space and detect and report interferences. Two-dimensional techniques can only depict objects at selected planes, and subjective judgment must be utilized in the identification of interferences. Three-dimensional physical models represent all points in the model space, but these models are extremely expensive to prepare, and human error is often introduced when drawings are prepared from these models.

-

-

Improved Production Work Packages: This benefit was not foreseen, but it has proven to be a key element in die design plan. Once a CAD model has been built and interference checked, construction drawings can be extracted in the format that is the most cost efficient. The SA'AR 5 work packages have been prepared to support each of the construction phases. Each of these packages contains only the irifotTtianon and material needed to support that particular work operation. This concept frees the craftsman from picking his work off of a large systenvonented drawing. Separate packages are usually uieuaied for shop fabrication, assembly preoutmnng, and final outfit work. In addition, special packages are prepared to support operations such as machinery packaging. Computer Aided Manufacturing: Machines for steel and aluminum plate cutting, sheetrnetal fabrication, and pipe ' bending are controlled from computer data bases maintained by Engineering. These data bases are prepared from product models as an integral pan of the design process.

-

Increased Communication. Teamwork, and Productivity: In process CAD designs are more accessible to other members of the design team than are manual designs, since the work of other individuals can be called up on CAD terminals forreview.This feature, when combined with a co-located team approach, fosters better communication and teamwork. Increased productivity is achieved primarily through the elimination of redundant work using model libraries for such items as background arrangements, equipment models, and standard details.

-

Greater Customer Visibility: Using project review software. CAD models can be surfaced and used to present the developing design to the customer. This technique has proven useful both during design reviews and in the resolution of technical issues.

ZONE DESIGN AND CONSTRUCTION

Ingalls has utilized a modular construction strategy for over twenty years. Using this technique, the ship is split into a number of construction units called assemblies. The structural elements for each of these units are fined and welded.

227

and outfitting items and distributive systems such as piping, ventilation, and wire ways are installed at the assembly level. In the case of the SA'AR 5, assemblies will then be erected and welded and systems finalized to form the completed ship. The design strategy for the SA'AR 5 mirrors the construction strategy. The ship has been split into IS design zones, each of which contains several construction assemblies. Figure 4 is a profile of the ship illustrating these design zones. Detail design is organized into three distinct phases: functional design, zone design, and production design. These phases are discussed below: -

Functional Design: A systems-oriented, total-ship approach is taken during functional design. During this phase, basic engineering calculations are completed, equipment selections are made, and schematic diagrams are prepared for pipe, vent, and electrical systems. Longitudinal strength, superstructure air blast, and other basic structural analyses are completed. Key space arrangements are determined.and weight budgets are allocated to systems and components.

-

Zone Design: During this phase, a three-dimensional CAD product model is created for each design zone. This product model contains ail elements of the ship: including main structure, equipment arrangement, piping and ventilation systems, and hangers, wireways. waveguide, and foundations. This model is checked for interferences and all specification compliance.

-

Production Design: The design geometry is determined during zone design. The purpose of production is to present the design to shipyard uafuiuen in the most usable format possible. Separate shop fabrication and field installation work packages are prepared. Material allocation is a very important aspect of this design phase. Raw material is allocated to shops with fabrication packages, and completed shop sub-assemblies are allocated to preoutfitting and ourfining packages.

DESIGN TEAM ORGANIZATION

The SA'AR 5 design marked the first large-scale use of concurrent engineering at Ingalls Shipbuilding. The product development team included representatives from production planning, production engineering, shipyard craft supervision, and material semiring, as well as engineers and designers. The participation of production personnel began during functional design but intensified during the zone design phase. During this period, any producibiiiry features that impacted the basic design configuration had to be identified and incorporated into the developing C A D models. These features included basic manufacturing breaks, system routing, and machinery package boundaries. During the production design phase all C A D models were routed to planning for detailed definition of manufacturing units and for work package billing. This was done prior to extraction of work package* by Engineering so that these decisions could be reflected in the development of the work package. In addition. C A D models were screened for material availability and standardization prior to work package preparation. The engineering team for the SA'AR 5 design consisted of a matrix organization in which selected principal engiHavat Engagers Journal. May 1992

151

neers had responsibility for ship systems and technical areas, and selected principal designers had responsibility for design zones. Priricrpal engineers were assigned for fourteen tedmical areas. Each of these engineers supervised a group af other engineers who performed analyses and developed systems within each of the teefmical areas. Principal engi(•eers also served as the primary customer for technical matters. PrniCTpal designers, working under the supervision of C A D design supervisors, controlled the development of the design within each design zone. These principal designers took the lead role in resolving arrangement issues within their design zones. Design zones were illustrated in Figure 4. Areas of responsibility for principal engineers are listed below: Naval Architecture and Ship Signatures Ship So-uctures Weight Control Outfit and Habnability Noise.

The key element in the plan for implementing C A D / C A M technology is the product model. The product model is a 152

Examples of si attributes are properties such as weight, K G . material, spe fication, etc (Product models are done at the level of det that is considered appropriate by the design functio Model merging can eventually result in a model that refle the entire ship.

It is important to recognize that the product model de with "objects- such as valves, gas turbine engines, dec lights—not just lines, arcs, or cylinders. An extensive ar of 3D C A D modeling applications for ail disciplines of si design has been developed. The assignment of a part nu ber to an element provides a means through which intee tion activities can be efficiently accomplished. INTEGRATION APPROACH

Ingalls* automation approach has been to automate t areas of highest return. Approximately ten years ago t manufacturing and material functions were automated pri to the start up of development of C A D 3D modeling car. biliry. Systems for material reqturements planning (MRI rtuuerial cataloging, pipe beading, and sheetmetal flat p; tern development were already in place. Consequently, t goal was to interface data extracted from the 3D models these existing systems. On S A ' A R 5. the approach is to int grate systems and organizations.

Planning assigns work authorizations to models and validates MRP input. The final step is for Engineering to extract drawings and manufacturing data. C A D / C A M HARDWARE An important aspect of the system is the hardware integration and configuration. At Ingalls, c o n n ^ - a i d e d ^ u f a c turing (CAM) applications are processed on an LBM 3UW host computer. The C A D applications are processed on Hewlett Packard engineering workstations. Machine insrructions to drive the numerical control ( N O are stored on IBM mimcomputers and personal computers. These computer systems have been networked to rrunimize manual intervention. Figure 5 depicts the C A D / C A M hardware configuranon.

AN EXAMPLE OF HARDWARE/SOFTWARE LINKAGE

A good example of electronic transfer is heating, vennianon and air corKUtionmg (HVAC) system interfaces. An object is modeled in 3D ship space on a C A D workstation. The geometric parameters and material attributes are extracted from the 3D nwdel and transferred electronically to a Flat Pattern Development (FPD) routine that resides in the LBM host computer.

PROJECT REVIEW CAPABOJTY

Among the more significant capabilities made available through the implementation of software technologies is the Project Review process. Engineers, planners, and craftsmen have historically used derail design drawings to define arrangements and installation procedures. Optimum workability was determined through the experienced visual interpretation of these documents, andrequireda mental conversion of these two-dimensional images into three-dimensional representations as they actually appear on board ship. The Project Review capability involves both dedicated hardware in the form of a workstation integrated into the C A D / C A M communications ring, and software that extracts product model geometry data. These data are rendered into colored and shaded images from the actual design product model and are used to ensure correct and optimum planning of ship construction. (Figure. 7) Concurrent engineering is a term becoming more often heard as a means of achieving higher quality designs and more efficient manufacturing. Ingalls Shipbuilding is actually and actively employing this technique by co-locating planning and production personnel with the product designer throughout the design process. This merging of craftsmen and designers from

the outset of a program is done with a single goal in mindmaxuTuze produdbiiiry. The principal tool used to achieve t goal is the Project Review Terminal (PRT). This terminal is a workstation configured to support creation of a realistic graphic depiction of design wire-fra models. These colored and shaded images reflect the mo as it appears to the craftsmen. It is capable of being viewed from any angle or from any distance. It can be verted from its design orientation to depict in full detail hi it may appear in specific stages of the construction proce A "blanking" feature allows different systems which s eventually co-located in a common compartment or space be optionally shown or deleted. As an example, pipir which may be installed prior to ducting may be shown wi out the confusion of showing the duct images that will t be present to the craftsman. In this case, the duct is said be "blanked." Later, when the craftsman is installing t duct, all of the data will be visually available for revie These kinds of features improve routing of distributed s\ (ems design and installation. The equivalent of a "wa through" the design can even be created and all aspects oi given area reviewed to whatever degree of detail is appr priate (Figures 8 & 9). Modifications and improvements c be defined and evaluated at the terminal and can be quick incorporated into the design product model. The Project Review Methodology usage continues to e pand. Terminals are being installed throughout the manufa turing areas for quicker access to craftsmen and manag ment. Terminals are being acquired to accurately acce progress, better understand design problems, and come better and more complete solutions. This has proven that ti PRT and the improved communication links that it has pr vided is one of the most valuable tools in the Ingalls' tec* nology toolkit. FUTURE DEVELOPMENTS The paper thus far has addressed the application C A D / C A M to the S A ' A R 5 design and construction. Th section looks to the future and the inevitable integration computer-aided engineering (CAE) to an operative ar complete C A D / C A M system. The emphasis placed on tl manufacturing end of the C A E / C A D / C A M spectrum w; dictated by the obvious pay-back associated with ship co strucnon. Our objective in the next few years is to eiihani the linkage of C A E within the system in order to achieve e: gineenng economies as well as a superior product.

In piping design, our intent is to initiate the produ model data base in the engineering phase, performing pi; stress and flow analysis on schematic layouts and inrrodu ing material control early in the engineering/design proces Stress and flow analysis will be refined as the design pn grosses within the constraints imposed by the engineer. In the area of structural design, the early model deveiot ment will be interfaced to MSC NASTRAN as required ft stress and shock/vibration analysis. The development, ana ysis. and correction of structural elements of the same pro uct model used to generate manufacturing aids will signif cantly reduce design time. It also ensures a produi relatively free of normal transport errors associated with tf

mampuiarion of models in off-line hardware and software ^ T u r i r d example of future C A E linkage is ship weight momtoring and control. Associativity is the ^ < W ^ t ° characteristics tied to discrete elements of a product model. One obvious characteristic is unit weight which, when combined with unit location, provides all of the information required for a design weight analysis. The design stability calculations can be performed by linking the product model with the weight analysis system, thereby eliminating manual loading of the system from detailed design druwincs As previously discussed, me ability to inspect and manipulate a shaded model of the design zone has added a new dimension to production planning. The sequencing( andâctual installation of distributed systems, for exantpleânoe planned and practiced on the partment models contain everything modeled by the designers in their exact locations. This exact «presentanon of the delivered ship, along with its associated data base, can be used by the customer for any number of applications, ranging from material ioentification to damage control trauung^ Although no one can predict the exact course of future developments, the remarkable ^ , biliry foreshadows a future with real-tune tours through Product models and industrial " W ^ J - * virtual reality; the ability to not only enter the model but touch and change it in real time. m

SUMMARY This paper describes the evolution of C A D / C A M technology at Ingalls Shipbuilding, culminating in the first complete C A D design of a surface warship.

The use of connwters to aid the design and manufacture of a ship is not new. What excites the ship designer about today's technology is the enormous power of the relatively êxpensive hardware and efficient software. There is no limit to the possible applications of this technology to ship design and life cycle support. We realize that we have only begun to exploit the available capabilities. For once, we are not watting for a new breakthrough to accomplish our goal. We need only to apply what's available and manage that apPh

Tteauthors are proud of their contribution to the industry's first step and we hope to continue shaping us inevitable growth. REFERENCES lindgren.

VERSLAG CV USERCONFERENCE EN USERMEETINGS D.D. 19 T/M 22 SEPTEMBER 1993 TE KANSAS CITY

Datum : oktober 1993 Rapportnr. : BSW/93-17 Auteurs : Wim Verbruggen Frans van Dam Status : Definitief

INLEIDING

Deze userconference was de tweede conferentie in de VS, waarin alle produkten van CV (Computervision, onze CAD leverancier van DIMIII) aan de orde kwamen. Tevens werden de oude gebruikersgroepen omgevormd tot een totale usergroup, met daarbinnen speciale aandachtsgebieden. De userconference bestond uit een aantal lezingen; een groot aantal demo's van CV produkten; een zogenaamde vendor fair en een aantal usermeetings. In dit verslag wordt kort ingegaan op ieder onderdeel en op de meeting die we met de CV vertegenwoordigers gehad hebben. Voor overzicht totale conference zie bijlage 1.

Samenvatting en conclusies

Stond tot voor kort het 3D-ontwerpen nog centraal op de agenda, er is nu een trend te signaleren dat men binnen bedrijven streeft naar het ondersteunen en verkorten (Time To Market) van het totale ontwerp-, bouwen onderhoudsproces. CV tracht hierop in te spelen met de nieuwe generatie CAD-software, de integratie van EDM met de CAD-software en CADdatastructuren, de PVS (Project Visualisatie Systeem) en datastructuren geent op STEP. 1.

De nieuwe generatie CAD-software richt zich op object-georienteerde technieken waardoor grote flexibiliteit ontstaat bij het toepassen van produktmodellen en geparametriseerd ontwerpen, zodat het 3D-ontwerp eenvoudiger kan worden ondersteund van conceptueel tot en met het definitief ontwerp. Voor bedrijven betekent dit, dat men zich eveneens moet richten op deze nieuwe technologieen, zoals het analyseren van applicaties op basis van object-georienteerde analyse methoden en het gebruik van object-georienteerde programmeermogelijkheden. Binnen de Bouwdienst wordt hierop reeds ingespeeld door de aanschaf van een objectgeorienteerd pakket voor het ontwikkelen van ontwerp-applicaties. Binnen CV bestaat grote belangstelling voor onze bevindingen. Daarnaast is door CV aangeraden de nieuwe ontwikkelingen op dit gebied in de PC-hoek (Visual Basic) te volgen en op hun inzetbaarheid te analyseren.

2.

Het managen van data door EDM wordt in de visie van CV niet alleen beperkt tot de informatie over de CAD-documenten, maar bevat ook de inhoud van CAD-documenten, dus tot op onderdeelniveau. Deze benadering is overigens weer mogelijk door de objectgeorienteerde technieken. De visie van de CAD-projectgroep is, dat hiervoor 2 verschillende managers gebruikt moeten worden; 1 voor het managen van documenten (TDIS) en 1 voor het managen van de onderdelen (het produktmodel). Een nadere analyse op dit punt is gezien de ontwikkelingen wenselijk. Naar onze mening zal in het komende jaar een definitieve strategie bepaald moeten worden voor het managen van engineering data, zodat nieuwe ontwikkelingen hierop kunnen worden afgestemd. Dit punt is overigens een "hot item" binnen veel bedrijven die wij ontmoet hebben op de userconference. De ervaringen bij bedrijven met PVS zijn zeer positief en met name managers zien in dit tool mogelijkheden de kosten van ontwerp en bouw van een produkt te reduceren. Dit tool wordt o.a. ingezet bij project-reviews, besprekingen met opdrachtgevers, op de bouwplaats voor het management van grote projecten en bij gebruikerstrainingen voor het bedienen van een fabriek. Door de CAD-projectgroep is hierop reeds in beperkte mate ingespeeld door de aanschaf van PVS-software. Implementatie binnen de Bouwdienst is voor de CAD-projectgroep een van de speerpunten. Doordat binnen bedrijven meer en meer met 3D-ontwerpsoftware wordt gewerkt, is een trend te signaleren dat men "intelligent" data wil uitwisselen. Hiervoor ontwikkelt men vertalers, die min of meer STEP-georienteerd zijn. Ook binnen de Bouwdienst loopt de inzet van 3D-ontwerpsoftware voor op de ontwikkeling van de STEP-standaard. Het tussentijds ontwikkelen van 'STEP-based' datastructuren en in een later stadium "STEP-based"-vertalers lijkt derhalve noodzakelijk. De wijze waarop de STEP-standaard tot stand komt. rechtvaardigt deze ontwikkeling. Gaande de ontwikkeling van STEP kunnen meer en meer van deze bedrijfsspecifieke datastructuren in de STEP-applicatieprotocollen verwerkt worden. De ervaringen hiermee kunnen via TNO en CV gebruikt worden voor het ontwikkelen van een STEP-standaard. Ook binnen CV wil men voor de opslag van data niet wachten op de definitieve STEP-standaard, maar implementeert men flexibele oplossingen, die hierop aansluiten. Intussen is men actief in verschillende STEP-commissies.

De bestaande gebruikers groepen van CADDS, MEDUSA en DIMIII (ASCUS) zijn overgegaan in een geheel zelfstandige gebruikersgroep, los van Computer Vision, conform het A S C U S model. De plant design steering committee is omgebouwd naar de nieuwe A E C steering committee en richt zich op de nieuwe CV-aec produkten, samen met de CADDS5gebruikers. De eerste versie van de CV-aec engine (2D tekenen en 3D draadmodellen) komt begin volgend jaar beschikbaar op PC's. CV wil DIMIII niet ineens vervangen maar geleidelijk aan vernieuwen met de nieuwe CV-aec componenten. Technische details kon men echter nog niet geven. Visual Basic wordt de nieuwe programmeertaal voor de CV-eac produkten, die verder geheel object georienteerd zijn en zowel op PC's onder MS-DOS, als onder UNIX zullen draaien. Voor terrein modellering gaat men met MSL (de leverancier van MOSS) onderhandelen om op korte termijn MOSS onder DIMIII en CADDS5 te koppelen (zie ook bijlage 11).

Als Bouwdienst kunnen wij begin volgend jaar kennis maken met de CV-aec engine voor 2D tekenen en 3D draadmodellen. Voor de 3D applicaties blijven we het komende jaar ontwikkelen onder DIMIII, aangevuld met de MTEL toolkit als objectlaag voor de samenhang van de met DIMIII gemaakte onderdelen. CV heeft veel belangstelling voor deze ontwikkeling en houdt hierover contact met ons. Ten behoeve van de nieuwe NMT (3D vlakken/solids/aec parts) modeller hebben wij de voor ons benodigde functionaliteit aan CV gegeven.

Opening

De opening werd gedaan door de voorzitter van de CV gebruikersgroep die deze conferentie organiseerde. In tegenstelling tot de voormalige CV userclubs en de gebruikersgroep in Europa, is deze nieuwe gebruikersclub geheel zelfstandig met eigen statuten en een eigen budget. De structuur is dezelfde als die voormalige gebruikersgroep rond CALMA (ASCUS) en veel van de voormalige A S C U S bestuursleden maken deel uit van het bestuur van deze nieuwe CV usergroep. 3.

Lezingen

Inleiding Zowel door CV als door de gebruikers en twee onafhankelijke journalisten zijn een aantal lezingen gegeven. De meest relevante en interessante lezingen worden in dit hoofdstuk weergegeven. De folies of abstracts van deze lezingen zijn in de bijlage opgenomen. Een boek met alle abstracts van deze userconference ligt bij Frans van Dam en Wim Verbruggen ter inzage. 3.1

Trends in de engineering wereld

De eerste lezing werd gegeven door de chairman van CV, Russ Planitzer. Hij gaf de volgende belangrijkste items en trends voor de jaren 90 aan: het belang om snel nieuwe produkten te ontwikkelen (reactie snelheid, reduce time to market) en het vermogen om efficient kleine series te maken; kosten beheersing alleen is niet voldoende, men moet de behoefte van de klanten kennen en daaraan kunnen beantwoorden (Leverage (Value-added) core competencies); veel uitbesteden en werken met een netwerk van specialisten; internationaal denken en handelen.

Aan de hand van de diverse industrie-sectoren werd een en ander toegelicht en werd de consequentie aangegeven voor de benodigde CAE gereedschappen en informatie structures Reducties in ontwerptijd (z.g.n. T T M , Time To Market) met een factor 3 worden nagestreefd en haalbaar geacht. Tevens werd het aandeel van CV in de totale C A D C A M markt en haar integratie kracht aan de orde gesteld. Voor meer info zie sheets op bijlage 2. 3.2

Open Engineering Data Management CAD/CAE for Plant design. Marine & A C E (Architectural, Civil & Engineering)

Deze lezing werd gegeven door Vincent Chaillou, hoofd van de AEC (Architectural, Engineering & Construction) business unit van CV. In deze lezing werd ingegaan op het AEC marktaandeel van CV, de belangrijkste gebruikers; op de algemene gebruikers behoefte vanuit de AEC wereld en op de belangrijkste concurrenten van CV binnen de AEC wereld. Bij het maken van applicaties hecht CV grote waarde aan het kennen van de bedrijfsprocessen, zodat de informatie flow (EDM) en de applicaties (produktmodel) daarop kunnen worden afgestemd. De software-ontwikkelingen vinden thans vooral in India plaats, zodat men met dezelfde middelen veel meer kan ontwikkelen en zelfs een betere kwaliteit kan bereiken. Ook Singapore draagt als staat bij in de AEC ontwikkelingen die aldaar moeten worden uitgevoerd. Voor verdere informatie zie sheets van deze lezing op bijlage 3. 3.3

CVAEC ROADMAP 1993/1994

Deze lezing werd gegeven door M. Hall, hoofd AEC research en development. Op deze lezing werden alle A E C produkten van CV als een familie besproken. De AEC produkten van CV zijn: DIMIII (CALMA); CADDS(5)-AEC en Medusa en het nieuwe produkt CVaec dat ook op PC's zal draaien. Geleidelijk aan wil men de core (2D tekenmoduul, 3D modeller e.d.) onder deze produkten uniform maken zodat alle produkten naar de nieuwe generatie toegroeien en men de onderhoudskosten kan reduceren. Tussen CADDS-eac en DIMIII is een speciale koppeling gerealiseerd. Binnen grote (scheepsbouw) projecten wordt vaak tussen DIMIII gebruikers en CADDS gebruikers samengewerkt. Binnen CVaec is thans alleen de PVS (het Project Visualisatie Systeem) beschikbaar. Aan dit produkt wordt in een hoog tempo telkens weer functionaliteit toegevoegd. De gebruikers zijn er zeer enthousiast over. Het CVaec-CVp&id pakket komt in kwartaal 2 van 1994 beschikbaar in plaats van de oorspronkelijk geplande eind 1993. De CVaec-engine komt als eerste versie (met 2D tekenen t/m 3D draadmodellen) kwartaal 1 van 1994 beschikbaar en wordt thans op beta sites getest. Dit produkt lijkt sterk op Designview, doch ondersteunt tevens alle Window- opties (zoals b.v. OLE) op PC's en is uiteraard meer gericht op grafische toepassingen/tekenen. In de tweede helft van 1994 komt dit produkt ook onder UNIX beschikbaar. De enhancements voor DIMIII betreffen vooral de nieuwe userinterface onder UNIX, de algemene C-interface voor expertsystemen, de interface naar EDM, verbeteringen in labelling en dimensioning, verbetering van de performance en een verbeterde Parametric Component Modeler. Tevens wordt de opdeling in modulen verbeterd en zouden de jaarlijkse maintenance kosten gereduceerd worden. Voor de implementatie onder Digital Alpha is de keuze van het operatingsysteem nog een probleem. Onder V A X - V M S komen geen nieuwe versies meer uit behoudens z.g.n. buxfixing releases. Voor verdere informatie zie sheets van deze lezing op bijlage 4.

C A D / C A M goes to sea

Deze lezing werd gegeven door Michel Streif, hoofd Automatisering van Ingalls shipbuilding. Ingalls is een DIMIII gebruiker en heeft een omzet van ca. 1 miljard dollar. In deze lezing werd het volledig 3D ontwerpen van een 80m lange Corvette voor de Israelische marine getoond. Het ontwerp was in zijn geheel in 3D opgebouwd en geintegreerd met de overige disciplines via databases. Vanuit dit ontwerp (produktmodel) werden alle tekeningen, stuklijsten en andere documenten ten behoeve van het ontwerp en de fabricage gegenereerd. Voor een aantal componenten in een schip is er zelfs een rechtstreekse koppeling naar de machines in de fabriek. Een soortgelijke lezing werd gegeven door een CADDS5 gebruiker die met Ingalls ook 3D modellen uitwisselt. De Amerikaanse Navy blijkt inmiddels een op PDES (STEP) gebaseerd 3D neutraal file formaat ontwikkeld te hebben dat voor deze gegevens overdracht wordt gebruikt. De abstract van deze lezing staat op bijlage 5. 3.5

Computervision and PDES/STEP

Deze voordracht werd gegeven door CV en ging in op de betrokkenheid van CV bij de STEP ontwikkelingen en op de organisatie van de diverse STEP werkgroepen en standaards. Voor de sheets van deze voordracht zie bijlage 6. 3.6

European users viewpoint on STEP

Deze lezing zou oorspronkelijk door T.N.O. op verzoek van CV gegeven worden. Daar T.N.O. zelf niet kon, is deze lezing door Frans van Dam gegeven, gevolgd door de video Getting in Step. De voordracht toont de behoefte aan goede standaards voor gegevens overdracht en hoe in Europa stap voor stap vanuit de huidige situatie naar de gewenste situatie wordt toegewerkt. In dit kader werd ook ingegaan op de Europese ontwikkel-programma's (Esprit, Eureka en Brite Euram) en een aantal PDI projecten binnen deze programma's. De interesse van de AECgebruikers voor deze voordracht was goed. Men zit vooral te wachten op Step standaards die direct kunnen worden toegepast. Voor de sheets van deze voordracht zie bijlage 7. De overige lezingen hadden een vergelijkbaar karakter en inhoud als de lezing van Ingalls, doch men was wat minder ver. Sommige lezingen waren zeer specifiek, bijvoorbeeld over interference checking, en zijn derhalve in dit verslag niet opgenomen. 4.

Uitwisseling van ervaringen

De uitwisseling van ervaringen bestond uit korte voordrachten van ca. 10 a 15 minuten, waarin een bepaald onderwerp door een aantal bedrijven werd aangesneden. Na de voordracht was er tijd voor vragen en discussie. Ondanks de beperkte voorbereiding waren deze sessies zeer leerzaam en informatief. In deze conferentie waren er twee blokken met ervarings-uitwisseling voor de A E C gebruikers. Een eerste blok betrof de meest recente ervaringen, aangevuld met toelichting wat de bedrijven deden. Het tweede blok was vooral gericht op de ervaringen rond engineering data management. 4.1

Laatste ervaringen, kennismaking met nieuwe gebruikers

In deze sessie heeft Wim Verbruggen, op uitnodiging door CV, een korte voordracht gehouden over de toepassingen van DIMIII binnen de Bouwdienst. Tijdens dit eerste blok mochten we kennis maken met de volgende drie CADDS(5)-AEC gebruikers: Bath Iron Works een scheepswerf met ca 100 werkstations; De county of Los Angeles een civiele gebruiker met ca 120 werkstations t.b.v. wegontwerp, terreinmodellen en GIS; De Bentham engineering group op het gebied van utiliteits bouw, plant design, waterbeheersing, GIS en terreinmodellen met ca 1500 medewerkers en 200 werkstations.

De meest recente ervaringen betroffen vooral de toepassing van de PVS (het Project Visualisatie Systeem) waarmee men door 3D modellen kan lopen en willekeurige informatie uit dat model kan opvragen. Vooral de managers zijn enthousiast. Wat op het eerste gezicht alleen presentatie leek, blijkt nu een uiterst nuttig tool te zijn voor het projectmanagement, de onderlinge communicatie met subcontractors en voor instructie. Veel gebruikers maken iedere twee weken een video waarin de voortgang van het ontwerp aan de hand van de 3D modellen wordt getoond. Ook op de Bouwplaats begint de PVS zijn intrede te doen als huipmiddel voor overleg en voor het bepalen van de montage volgorde. Voor instructie-doeleinden is men bijvoorbeeld al eens vanuit de uitlaat de motor ingewandeld. 4.2

Uitwisseling ervaringen met Engineering Data Management

De behoefte aan Engineering Data Management wordt algemeen onderkend, doch de invoering kost veel eigen inzet. Met name het overgaan van de oude papieren situatie naar het tijdperk met digitale gegevensoverdracht, kost veel inspanning voor het aanpassen van de werkprocedures en de acceptatie van digitale bestanden in plaats van papier. De DIMIII gebruikers hebben net als wij problemen met de relaties tussen modellen en tekeningen. Een aantal heeft in het verleden DMCS aangeschaft, doch het produkt wordt vanwege de vereiste inpassing in de organisatie nog niet geoperationaliseerd. Ingalls schipyards heeft een op Oracle gebaseerde engineering data manager (DSRS) met succes volledig ingevoerd maar hamert erop, dat men zelf de produkten moet kunnen toesnijden en derhalve een goede DAL&ORACLE programmeur in huis moet! hebben. (Customisation is necessary!!). De county of Los Angeles werkt ook met een Engineering Data Manager; in dit geval EDM van CV. Men heeft bewust de oude naam conventies voor files gehandhaafd en haar ambitie zo praktisch mogelijk gehouden. EDM wordt door hen voor zowel tijdelijke als blijvende data opslag gebruikt. De county adviseert net als Ingalls te zorgen voor: 1) 2) 3)

Analyse van de document procedures met uitgebreide gebruikers reviews en opleidingssessies. Eerst het werkproces te definieren. Het overtuigen van het management van het belang van een goed data management.

Over de toepassing van EDM was men erg te spreken, doch het eist extra computer power. Met name onderlinge coordinatie en communicatie wordt door EDM versterkt en men weet waar alles is. Vertaald naar de Bouwdienst-situatie blijkt, dat we met TDIS aan een zware klus begonnen zijn, die een stapsgewijze aanpak en een sterke terugkoppeling naar management en gebruikers eist. Met name het ontbreken van een eigen EDL/DAL programmeur en de kans op een te hoog ambitie niveau eist aandacht. Tevens kan de inzet van extra computer power op de file server nodig zijn. Tot slot gaf CV nog informatie over EDM. De link tussen EDM en DIMIII wordt verder ontwikkeld en de document en/of produkt structuur kan in de nieuwe versie grafisch worden weergegeven. Wereldwijd heeft men thans 10.000 stations op EDM aangesloten op ca. 250 sites. Voor verdere informatie zie sheets op bijlage 8.

Demo's door Computer Vision

Alle produkten van CV werden getoond in een groot aantal demo's. De demo over wereldwijde concurrent engineering met behulp van EDM en een aantal teleconferencing tools was interessant. Op de PVS (Project Visualisatie Systeem) werd de combinatie van geluid en beweging getoond door een vliegtuig langs de controle kamer van een verkeerstoren te laten vliegen. Tevens werd de toevoeging van spiegeling en extra lichtbronnen getoond, zodat men de beelden ten behoeve van presentatie nog realistischer kan maken. Tot slot hebben we een demo van CV-DORS, GIS en CADDS-AEC bijgewoond. Voor een totaal overzicht van de demo's zie bijlage 9. 6.

Vendor fair

Op de vendor fair waren ca. 25 bedrijven aanwezig. Opvallend groot was het aantal bedrijven dat zich bezig hield met gegevens-overdracht en systeem-integratie. Voor ons was er weinig nieuws onder de zon op deze Vendor fair. De deelnemende bedrijven aan deze vendor fair staan op bijlage 10. 7.

Usermeetings

De oude plant design steering committee voor DIMIII is overgegaan naar een bredere gebruikersgroep ten behoeve van de nieuwe CV-aec produkten. Men wil zich vooral richten op de toekomst en hieraan met behulp van krachtige kerngroep met maximaal 15 krachtige gebruikers richting geven. De CADDS-gebruikers en DIMIII-gebruikers zitten aardig op hetzelfde niveau en op dezelfde lijn. Medusa is nauwelijks vertegenwoordigd. In tegenstelling tot de mechanical users hebben de oude DIMIII gebruikers binnen CVaec de sterkste vertegenwoordiging. De nieuwe committee werkt op dezelfde basis als de oude plant design steering committee doch heet nu AEC-steering committee en kent naast plant design en shipbuilding ook een drietal Civil users (RWS, County of Los Angeles en de Benham group). De deelname van de USBR is onzeker daar de USBR vermoedelijk niet meer op de komst van een verbeterde terrein modelleur wil wachten en derhalve op een ander produkt overstapt. Behoudens de onzekerheid rond de USBR lijkt de merge met CADDS een goede zaak. De eerst volgende bijeenkomst is gepland voor eind januari 1994 in Boston. Men hoopt dan meer inzicht te krijgen in het inpassen van de CVaec engine in de bestaande A E C produkten. 8.

Bespreking RWS met C V

Aan het eind van de CV conference hebben we een ca. 2 uur durend gesprek gehad met Vincent Chaillou, hoofd A E C Business unit en John Parsons, hoofd A E C marketing. Tijdens deze bespreking zijn o.a. de volgende punten besproken:


Blad 9

8.1

Ontwikkeling CV-aec

8.1.1.

2D en 3D draadmodellen/tekenen

De CV-aec engine is thans als beta versie beschikbaar en komt begin volgend jaar op de markt. Deze versie draait onder Windows op PC's en gebruikt ook alle opties die Windows biedt. Verder lijkt het veel op designview en kan het naast 2D ook 3D draadmodellen aan. CV is op de hoogte gebracht van de evaluatie die de Bouwdienst voorjaar 1994 wil uitvoeren en zal ons in het eerste kwartaal 1994 deze eerste versie van de CV-aec engine ter beschikking stellen. Volgend jaar komt tevens een versie onder Unix beschikbaar en wordt P&ID onder dit pakket op de markt gebracht. Met tekenen en met 3D draadmodellen zou de Bouwdienst theoretisch de 2de helft van 1994 kunnen starten met de overgang naar dit produkt. De data koppeling en het migratie programma naar DIMIII is nog niet uitgewerkt. Men streeft naar een geleidelijke overgang. De programmeertaal van de nieuwe CV-aec engine is "Visual Basic-like", CV heeft ons gevraagd om met deze programmeertaal nader kennis te maken om te zien of er naast deze taal nog een zwaardere taal, bijvoorbeeld C + +, nodig is. 8.1.2.

3D vlakken en solids

Deze functies zullen in de nieuwe NMT modeller (eveneens onderdeel van de CV-aec engine) worden ingebouwd, doch deze is volgend jaar nog niet beschikbaar. Uiteindelijk moet deze modeller in alle AEC produkten worden ingebouwd, maar voor DIMIII kan men nog geen migratie pad aangeven. Voorlopig kunnen wij ons met DIMIII nog wel verder ontwikkelen met de staal ontwerp pakketten, ACL en de onlangs aangetrokken MTEL Toolkit. CV zal binnenkort meer informatie geven en ook kijken in hoeverre de ACL functies in de nieuwe NMT modeller aanwezig zullen zijn. 8.1.3.

Ontwerp-applicaties

Wij hebben CV duidelijk gemaakt, dat we onze eigen ontwerp-applicaties zo klein mogelijk willen houden en derhalve zoveel mogelijk basis functionaliteit van de nieuwe CV-aec engine verlangen. Op deze wijze wordt migratie zinvol, daar het bedrijfsspecifieke onderhoud dan veel kleiner wordt. CV wil graag met ons samen de nieuwe applicaties ontwikkelen en is met name geinteresseerd in de specificaties en de gebruikers-ervaring. Men wilde ook graag weten in hoeverre wij die mochten geven. Onzes inziens zijn daar geen beperkingen in, daar onze kennis in principe openbaar is en vooral tot doel heeft om zo economisch mogelijk de Nederlandse infrastructuur te bouwen en te onderhouden.

8.1.4.

Terrein modelleur

CV wil de contacten met MOSS verder aanhalen en wij hebben dat van harte gesteund. Op korte termijn gaat men met Moss in onderhandeling om een interface tussen Moss met DIMM en CADDS te realiseren. Vanuit DIMIII en CADDS kan men dan de MOSS terreinmodelleur gebruiken. Op langere termijn hoopt men MOSS ook op de nieuwe CV-aec engine aan te sluiten doch dat is een groeiproces voor beide partijen. Ter informatie is een brief van MOSS aan CV als bijlage 11 aan dit verslag toegevoegd. 8.2

DXF convertor

Wij hebben aangedrongen op een spoedige verbetering van de aanwezige DXF convertor. CV vroeg zich af waarom wij de concurrerende Hillman convertor niet hadden en gaf daarmee de ernst van het probleem zelf aan. Op korte termijn zal men aangeven of wij via een inruilactie vanuit CV op deze convertor kunnen overgaan of dat er verbeteringen op komst zijn. RWS zal de laatst geconstateerde fouten opsturen naar CV.


Blad 10

8.3

A C L ontwikkelingen

CV-Design lijkt geen alternatief voor de ACL modeller te zijn gezien de ontwikkelingen rond de NMT modeller. Men is zeer geinteresseerd in onze ontwikkelingen met de MTEL Toolkit en de relatie met Caroline Informatique. In deze ontwikkelingen is ons steun via een CV-contact persoon toegezegd. 8.4

STEP ontwikkelingen

De in Europa geplande bijeenkomst met A E C gebruikers voor de ontwikkeling van applicatie protocols is weliswaar uitgesteld, maar gaat wel door; vermoedelijk eind oktober/begin november. Men is tevens geinteresseerd in ons commentaar op STEP in relatie tot Wegontwerp (zie bijlage 12) en vraagt om dit stuk naar de CV contact persoon in STEP Dave Duffett met afschrift voor Vincent Chaillou toe te faxen. 8.5

Inplementatie op VAX-ALFA

De nieuwe generatie werkstations van Digital draait onder drie verschillende operating systemen welke onderling voor CAD niet compatibel zijn. CV heeft implementatie op VAX-ALFA onder het OSF-UNIX operating systeem op de planning staan, maar betwijfelt of Digital dit operating systeem wel 100% wil ondersteunen. Digital schijnt de voorkeur te geven aan Windows-NT. Als RWS hebben wij gezegd dat als we naar UNIX willen, voor ons de overgang naar HP-UNIX een aanvaardbaar alternatief is. Wel vinden wij een keuze tussen meerdere UNIX platforms vanwege concurrentie overwegingen gewenst. Op VAX-ALFA is voor ons, op korte termijn, een implementatie onder V M S het meest wenselijk daar we dan zowel voor ons huidige operating systeem VMS als voor UNIX (onder HP) kunnen kiezen.
