Q

The two different windows for drawing, each having their own scales and rules

A

Model space and Paper space

17
Q

Model space attributes

A
  1. Real world scale 1:1 and typically in units of metres
  2. The area where the drawing elements are created
  3. Can draw in either 2D or 3D

18
Q

Paper space attributes

A
  1. Paper scale, typical scale of 1:1000 in units of millimetres
  2. Drawing in 2D only
  3. Set the paper size of the drawing
  4. Location of title block and annotations
  5. Where you layout your drawing and decide what scale to display it at based on the properties of the view points created
