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.

 When trimming a surface or region with a 3D curve in an

angled, parallel or perspective view (for example, the default

perspective view), the cutting geometry is projected onto

the surface in a direction parallel to the Z direction of the

current UCS.

Projects the geometry in the +Z and -Z axis of the current UCS.UCS

The surface will only be trimmed if the cutting curve lies on the

surface.
