- Selected State
-
If you want to keep the region you trimmed away, select Keep. To discard the region you trimmed away, select Discard. The default is Keep.
- Shrink Surface
-
Causes the underlying surface to shrink to just cover the retained regions. This permanently changes the surface geometry and cannot be restored by untrimming, but Undo will still work.
- Fitting Tolerance
-
Specifies how precisely the Trim Tool uses the shape of the curve-on-surface when it trims the surface. The default value works well in most cases, but you can use a smaller value to increase precision.
- Keep Original
-
The original surface is retained after the trim is performed. If the surface and the curve-on-surface were created with construction history turned on, you must keep the original geometry.
