How to trim 3D solids with other 3D solid (3D trim).

A - answer If you need to trim 3D solids, you should use the command SUBTRACT, the standard TRIM does not work on 3D objects.

Create a copy of the trimming solid (cutting edge) and subtract this duplicate from the trimmed objects. If the trimming object is just a thin solid, only a slit may be made in the trimmed objects, but they remain intact, together as one body. In this case, use the command SOLIDEDIT with the option Body > Separate. Then erase the dangling parts outside the trimming border.

Another option for trimming is to convert the trimming object to Surface and use the command SLICE.

The first option is illustrated in the video:
