If the SURFACEASSOCIATIVITY (page 1452) system variable is set to 1, the
trimmed surface updates whenever the trimming edges are modified.
List of Prompts
The following prompts are displayed.
Select Surfaces or Regions to Trim Select one or more surfaces or regions
to trim.
Select Cutting Curves, Surfaces, or Regions The curves that can be used
as a trimming edge includes lines, arc, circles, ellipses, 2D polylines, 2D spline
fit polylines, 2D curve fit polylines, 3D polylines, 3D spline-fit polylines,
splines, and helixes. You can also use surfaces and regions as trimming
boundaries.
Select Area to Trim Select one or more regions on a surface to remove.
Extend Controls whether the cutting surface is trimmed to meet the edge of
the trimmed surface.
Projection Direction The cutting geometry is projected onto the surface.
Controls the projection angle as follows:
Automatic
 When trimming a surface or region in plan, parallel view
(for example, the default Top, Front, and Right view), the
cutting geometry is projected onto the surface in the view
direction.
 When trimming a surface or region with a planar curve in
an angled parallel or perspective view, the cutting geometry
is projected onto the surface in a direction perpendicular
to the curve plane.
