Trim Surface
You can use a surface, plane, or sketch as a trim tool to trim intersecting surfaces. You can also use a surface in conjunction with additional surfaces, as mutual trim tools. Trim surface includes the following options:
To trim a surface:
-
Create two or more surfaces that intersect at one or more points, or create a surface that intersects with a plane or has a sketch on its face.
-
Click Trim Surface on the Surfaces toolbar, or click Insert, Surface, Trim.
-
In the PropertyManager, under Trim Type, select a type:
-
Standard. Trims surfaces using surfaces, sketch entities, curves, planes, and so on.
-
Mutual. Trims multiples surfaces using the surfaces themselves.
-
Under Selections, choose from these options:
-
Trim tool
(available with Standard selected under Trim Type). Select a surface, sketch entity, curve, or plane in the graphics area as the tool that trims other surfaces.
-
Surfaces
(available with Mutual selected under Trim Type). Select multiple surfaces in the graphics area for Trimming Surfaces to use to trim themselves.

Remove selections. Discard the surfaces listed under Pieces to Remove . Intersecting surfaces not listed under Pieces to Remove are retained.
-
Select surfaces in Pieces to Keep or in Pieces to Remove , based on the trim action.
