- 2. Qualification BTEC EXTENDED CERTIFICATE IN ENGINEERING Start date 08/10/2017 Deadline 26/10/2017 Assessor Assignment title 10.2 Produce a CAD drawing using orthographic projection methods The purpose of this assignment is to: a) Be able to produce isometric and orthographic CAD drawings b) Be able to store and retrieve engineering drawings for printing Scenario You are working in the CAD office of Enviroplay, who supply toys for young children and make them using sustainable materials. The development team have asked you to produce the engineering drawings of a toy that is currently being considered to add to their range. Sketches of the components have been supplied to you and are shown below. The current design thoughts from the development team are as per the drawing below: • The train is to be made from sustainably sourced timber • The wheels are attached by drilling a 4.5mm dia hole through the base and a stopped hole 5mm deep, 4mm dia on each wheel to accommodate a 4mm dia dowel, 65mm long. Include dimensions, notes, etc., as necessary for the product modelling team to create a prototype. Task 1 Produce an isometric drawing of the toy train using the CAD software available, from the information supplied to current British Standards guidance (e.g. BS8888, BS3939, and BS2917). WHEELS 35mm DIA CAB, BASE & WHEELS 10mm THICK THROUGHOUT FUNNEL 20 LONG 10mm DIA ENGINE SHOULD FIT INTO A BOX MEASURING 120 X 82.5 X 70mm
- 3. Hidden detail need not be shown. Note that Enviroplay use the layout for a standard engineering drawing setup which you may well have saved previously as a template when carrying out assignment (10.1). Drawing should be numbered ENVIROPLAY DRG0005 This provides evidence for P3 Task 2 a) Produce orthographic detail drawings of the individual components of the toy train (boiler and funnel, base, wheels & axles) using the CAD software available, to current British Standards guidance (e.g. BS8888, BS3939, and BS2917). Hidden detail should be shown. Use the layout for a standard Enviroplay engineering drawing setup, saved previously as a template when carrying out assignment (10.1). Drawings should be numbered ENVIROPLAY DRG0001-DRG0003 This provides evidence for P2 b) Produce an orthographic assembly drawing containing three views of the toy train using the CAD software available, to current British Standards guidance (e.g. BS8888, BS3939, and BS2917). Hidden detail should be shown. Use the layout for a standard Enviroplay engineering drawing setup, saved previously. The drawing should be numbered ENVIROPLAY DRG0004 and parts detailed by DRG0001- DRG0003 are required to be indicated on the drawing.
