Combine Bodies

In a multibody part, you can combine multiple solid bodies to create a single-bodied part or another multibody part.

You can add or subtract bodies, or keep material that is common to the selected bodies.
You can only combine bodies contained within one multibody part file. You cannot combine two separate parts. However, you can create a multibody part by using Insert Part to place one part into the other part file. Then you can use Combine on the multibody part.
It is strongly recommended that you do not use the Combine feature to combine weldment bodies. It is not always possible to calculate the cut list properties accurately for a body created using the combine feature.
In these examples, the multibody part contains two separate extruded bodies.
Add Combines solids of all selected bodies to create a single body.
Subtract Removes overlapping material from a selected main body. You can make the main body transparent to help you select bodies to subtract.
Common Removes all material except that which overlaps.
