3D CAD

Learning Intentions 3D Modelling- Extrude, Revolve, Fillet Etc. 3D Modelling- Advantages Animation & Simulation- Advantages

3D Modelling- Extrude Extrude Join: Adds the volume created by the extruded feature to another feature or body. The extrusion tool is used to add depth to a sketch to transform it into a 3D model as shown below Cut: Removes the volume created by the extruded feature from another feature or body.

3D Modelling- Revolve Revolve Profile is the sketch Creates a 3d model or feature by revolving a profile around an axis. Profile is the sketch Axis is the centre line you want to revolve round

3D Modelling- Alterations Shell Fillet Chamfer The shell tool allows you to remove surfaces and hollow out any shape or feature. The fillet tool allows you to round any selected corner or edge on a model. The chamfer tool allows you to remove an angular section along any selected corner or edge.

3D Modelling- Advantages Models can be easily sent electronically all over the world Components can be used in different projects Ease of modification- can be changed easily Ease of storage- as opposed to large scale models

Animation & Simulation Computer Animation Computer Simulation

Animation - Advantages Example: Race Car Safer No risk of crashing for driver Cheaper No running cost e.g. petrol or new parts Testing Can be tested to see how it would cope in a crash situation
