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:

  1. 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.
  2. Click Trim Surface on the Surfaces toolbar, or click Insert > Surface > Trim.
  3. 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.
  4. 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.
    • Select a trim action:
      • Keep selections. Retains the surfaces listed under Pieces to Keep surface_pieces_to_keep.png. Intersecting surfaces not listed under Pieces to Keep are discarded.
      • Remove selections. Discard the surfaces listed under Pieces to Remove surface_pieces_to_keep.png. Intersecting surfaces not listed under Pieces to Remove are retained.
    • Select surfaces in Pieces to Keep surface_pieces_to_keep.png or in Pieces to Remove surface_pieces_to_keep.png, based on the trim action.
  5. Under Surface Split Options, select an item:
    • Natural. Forces the boundary edges to follow the shape of the surface.
    • Linear. Forces the boundary edges to follow a linear direction from the trim point.
    • Split all. Display all splits in the surface.

  6. Click
