Alias: SU

Note: In the BricsCAD Lite license level, the command applies to region entities only.


Performs Boolean subtraction operations on 3D solids and 2D regions by removing the overlapping portions of one from another.


Select the object to subtract from and the objects to subtract. The DELETETOOL system variable determines whether the source entities are deleted or retained.

Note: The result of this command is sensitive to the order in which you select entities.
  • A cylinder was subtracted from a sphere (1) and vice versa (2).
  • The order in which you select entities also applies to regions.
Note: You can interrupt the command by pressing the CANCEL button.
