To Trim 3D Freeform Spaces

You can trim a part of an existing 3D freeform space by trimming one of its surfaces.

Note: This procedure is valid for non-associative spaces only. If you perform it on an associative space, it will loose associativity after exiting the in-place edit mode.

Trimming a 3D space

1. Verify that you are working in a 3D isometric view.
2. Select the space you want to trim along the horizontal or vertical plane.
