Trim two adjacent surfaces by extending intersections to complete the trim.

In the Feature toolbar, within the Offset surface or Plane dropdown command menu:

Feature toolbar indicating Mutual trim icon

The Mutual trim feature tool allows you to trim two adjacent surfaces by extending intersections to complete the trim.

Click the Mutual trim feature tool on the toolbar. Select the First surface in the graphics area. Click the Second surface in the graphics area. For each surface, click the Keep opposite side arrow to indicate which side is kept after the trim operation.

By default, with Merge checked, both surfaces are merged into one surface. Uncheck if you want to keep both surfaces.

Click the green checkmark to apply the trim and close the dialog.

  1. Click Mutual trim icon.

  2. Select the first surface.
  3. Select the second surface.
  4. For each surface, click the Keep opposite side arrow to indicate which side is kept after the trim operation:

  5. Optionally, check the Merge box to merge both surfaces into one surface.

The surface (or surfaces) are listed in the Surfaces list.

This lists the collection of surface feature tools. This is not an exhaustive list. Additional Feature tools may be used when modeling surfaces. See Surfacing for additional information.

  • Thicken - Add depth to a surface. Create a new part or modify an existing one by giving thickness to a surface and converting it to a solid, adding or removing material from an existing part or surface, or intersecting parts in its path.
  • Enclose - Create a part by selecting all boundaries surrounding an empty space to form a solid. Use any set of surfaces and solids (including planes and faces) that intersect each other or connect at a boundary to create a volume.
  • Fillet - Round sharp interior and exterior edges and define as a standard constant radius, more stylized conic, or variable by selecting Edge fillet. Optionally apply a Full round fillet to create a seamless blend of one or more faces between two opposing sides.
  • Face blend iconFace blend - Round sharp connected or disconnected interior and exterior faces to create a seamless blend between the faces or detach the blend to create new faces, defining a radius or constant width. Further define the blend cross section (rolling ball or swept profile), symmetry, control, trim, constraints, and limits.
  • Delete face - Remove geometry from a part. Select whether to heal the surrounding faces (by extending until they intersect), cap the void, or leave the void open. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
  • Move face - Translate, rotate, or offset one or more selected faces. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
  • Replace face - Trim a face or extend a face to a new surface. This Direct Editing tool is especially convenient if you don't have the parametric history of the part, as is often the case with an imported part.
  • Offset surface - Create a new surface by offsetting an existing face, surface, or sketch region. Set offset distance to 0 to create a copy in place.
  • Loft feature icon Boundary surface - Create or add a surface specified by its boundary profiles.
  • Fill - Create a surface (or a part from surfaces) by defining boundaries and refine the surface with boundary conditions (instead of requiring the use of reference surfaces).
  • Move boundary - Move boundary edges of a surface in order to extend or trim it.
  • Ruled surface - Create a new or additional ruled surface from an existing edge or multiple edges of a sketch region.
  • Mutual trim - Trim two adjacent surfaces by extending intersections to complete the trim.
