Trims one or more surfaces along the input element you define. You can use a curve, reference plane, or another surface as the input element.

• If using curves,

  • They must lie on the surface you are trimming. Use the Project Curve command to project the curve onto the surface first.

    

  • Closed curves that do not completely lie on the surface are not supported.

• If using a surface as the trimming element the surface must touch or intersect the target surface.

  • If the curve or surface boundary does not extend to the edges of the target surface, the trim boundary element is extended linearly and tangent to the input element.

    Note:

    Surface 1 is used to trim surface 2. Since surface 1 does not extend to the edges of surface 2, linear extensions are added to the trim boundary element. The input element you select as the trimming tool surface 1 is not modified.
