WARNING! Watch out for the 3rd column "Assessment Task" This
tells you what you need to do. For example, in Exercise 6: Support Block (p16) Part: This means you
only need to make a 3D model (.ipt)
Bracket (p18)

MW2 |
Assembly model of main structure and arm of the mummer wrapper project. Must have roatating arm and other movable components (such as the cloth rolls). Detailing of some hardware should be included but a fully detailed completed assembly model is not expected. As a conceptual assembly model with motion capability, you should demonstrate appropriate use of sub-assemblies, and provide suitable constraints to allow dragging of parts or sub-assemblies (e.g. arm rotation, up/down movement of rolls). Alternative: Assemble a human model, imported from the internet (e.g. GrabCad) and scale it to appropriate percentile (95% stature). You can import files of type Parasolid, step, iges, but native Inventor models would be easier. Use this one: man and pedals.STEP (Open>Import>save. Then constrain the assembly) |
