Question 2 - CAD Drawing (50%) CLO2 Demonstrate the use of CAD/CAM tools in creating 2D and 3D models (P3, PLO2) Select an object that you can carry in your hand. Create a model of the object in a 3D CAD. Show the picture of the actual object and the 3D model (an example is as shown in Figure 1). The model should represent the scaled size of the object, with approximate accuracy (+1mm). The object should contain more than one basic features (e.g. combinations of rectangle, sphere, and cylinder with holes, slots or chamfers). Figure 1 3D Model Example Develop the 2D CAD drawings with isometric and 3rd angle orthogonal projection in a drawing template (as shown in Figure 2). All units are in millimetres. Note: Your submission to the Online Assignment System (OAS) includes the photo of the object and the CAD drawing in pdf format. Use a photo that will be able to indicate the actual size of the object. For example, provide a photo of the object with a ruler. Marks are given for complexity of the object based on the number of features (1 mark for a feature, up to 10 marks). Write down the number of features in the drawing, as shown in Figure 2. The tutor has the right request a student to show the actual object to check for the validity of the model at random. A model with dimensions too far different from the actual object can be requested to be redrawn.
Remember: Do not copy the example given in this question. ISOMETRIC VIEW Number of features: 11 LEFT SIDE VIEW UNLESS OTHERWISE STATED ALL DRWN DIMENSIONS IN MILLIMETERS. DATE: DWG.
