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.
