3.

The name of the Mechanical Engineering Drawing and Design/CADD Mechanical Engineering Drawing and Design covers the use of computer Aided Drawing & Design (CADD) technology in the preparation of graphical models, drawing, paperwork and files containing all information necessary for the manufacture and documentation, of part and component typical of solution to mechanical engineering problem.

The test only consist the practical work. The theoretical is limited to that necessary to carry out the practical work and reflect that of an entry Mechanical Engineering Drawing and Design

Practical Work 3.1. Practical tasks will be given sketching, detail drawing, individual physical part and assemblies. Collection of information from these sources will require reading of print, sketches, drawing, engineering tables, and manual. Additional information will be obtains from direct measurement of actual part supplied and or from scaled drawings. Problem will be requiring solutions in the form graphical and textual description, sufficient to communicate successfully the information necessary for manufacturing of these component assemblies in industry. 3.2.

Competition Project Categories 3.2.1.

Producing engineering drawing from dimensions taken of an actual part or from isometric drawing (3D). Will be done by measuring aids such as, vernier calipers, bevel protectors, radius gauge etc. as by triangles, dividers, arcdegree and then transfer the measuring result to paper sketches.

3.2.2.

Producing drawings model isometric and engineering drawing from dimension taken of drawing of orthographic (2D). Measuring will be done by triangles, dividers, arc-degree etc.

3.2.3.

Preparing an assembly drawing with all necessary views, sections, general dimension and animations. Based on draft of them and notes that contain all information on design, producing detail part drawing for manufacturing containing all necessary information for logical manufacturing processes such as:  Complete shape description of the component  General dimensions  Fundamental dimensions and tolerances  Geometric tolerances of front and position  Surface finish symbols  Created and make animations material
