Question 2

Describe 4 features of CAD/CAM software and give one advantage of each.

Answer 2

• Hatching or rendering
  Different finishes or materials can be displayed, can do many ‘what if’ type investigations.
• Zoom
  Enhance parts of a drawing to make it bigger, helps produce work of more detail or add detailed design.
• Rotate
  Rotate in 3D across X, Y and Z axis, see design from all angles on the outside.
• Walkthrough
  Can visit rooms etc in 2D, allows spacial awareness of what the design looks like in relation to other features
• Costing
  Produce estimate of cost of building materials, can help the designer work out a budget
• Stress and Strain
  Working out the weights materials can take, avoids disasters later on when building as the designer should build well within the safety requirements
• Wire drawings
  See design without any finishes or solid form, helps with perspective and working out stresses and strain areas
