Subtract

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

Note: This result of this command is sensitive to the order in which you select entities. Here, a cylinder was subtracted from a sphere (left) and vice versa (right).

Accessing the Command

command bar: subtract
alias: su
menu bar: Model | 3D Solid Editing | Subtract

Prompts you in the command bar:

Select ACIS object to subtract from: (Choose one or more 3D solids and/or 2D regions)

Entities in set: 1

Select ACIS object to subtract from: (Choose more ACIS entities, or else press Enter to continue)

Select ACIS objects to subtract: (Choose the second set of one or more 3D solids and/or 2D regions)

Entities in set: 1

Select ACIS objects to subtract: (Choose more ACIS entities, or else press Enter to continue)

The DELETETOOL variable determines whether the source entities are deleted or retained.

The order in which you select entities also applies to regions:
