Scale and Unit of Measurement
The Main scale of active drawing and Unit of measurement functions enable you to make subsequent changes to the current drawing or choose another dimensioning unit.
Note:
- Please note that you can also assign view scales in 3-D and part scales in 2-D.
- The unit of measurement, the selected scale and the position of the coordinate system origin simultaneously define the screen display.
