Card 1comparison

Question

Surface model vs solid model?

Answer

A surface model defines the outer skin only, used for complex curved styling. A solid model defines the whole volume, so it has mass, a centre of gravity and material properties, and can be analysed or manufactured.

Question

What is generative design?

Answer

The designer supplies constraints — loads, fixings, material, allowed space — and the software produces geometries that meet them, often shapes a designer would not have drawn.

Card 3definition

Question

What does finite element analysis (FEA) do?

Answer

Divides a part into many small elements and predicts stress, deflection and where it will fail under a stated load, before anything is manufactured.

Question

What do digital humans, VR/AR and haptics have in common?

Answer

All three simulate USE rather than form or strength: reach and clearance, being inside the design at full size, and force feedback on a virtual control.
