Subtracting 3D Solids or Regions

The Subtract command creates a composite region or a 3D solid by subtraction.

To subtract regions or 3D solids from each other:

1. Click Solids > Solid Editing > Subtract (or type Subtract).
2. Select the regions or 3D solids to subtract from.
3. Select the regions or 3D solids to subtract and press Enter.
4. From the objects in the first selection all objects in second selection are subtracted. The original objects are deleted.
5. 

Note: If a selection set contains more than one object, the union operation is applied to it first:

Vresult = (V1[Set1] + V2[Set1] + .. + Vi[Set1]) - (V1[Set2] + V2[Set2] + .. + Vj[Set2])
