The Intersect with Keep function works exactly the same as the Boolean Intersect operation except that all material normally removed during the operation is retained in the result. When a boolean operation is completed, you will be left with the original bodies as well as the result of the operation. You can select solids in part references as tool solids. In all such cases, the tool solid (which is a solid in a part reference) is never destroyed.

Using the Function:

1. Select Intersect (Keep) from the Modify>Boolean submenu.

2. Select the first solid to intersect.

3. Select the additional solid(s) to intersect with the first. All bodies will be retained, and the intersection will be made.
