Project Trim

(3D only) Used to:

Tool Setting	Effect
Direction	Sets the direction of the projection. Orthogonal — Projection is taken normal to the cutting profile. View — Projection is taken normal to the active view. Vector — Direction of projection is determined by two points. Normal to Surface — Projection is taken normal to the plane of the surface being trimmed.
Output Mode	Sets the method used to trim the surface. Trim Surface — The region either inside or outside the projected curve is trimmed away. The identified portion of the surface is retained. Split Surface — The surface is divided into two regions, one inside the projected profile and the other outside the projected profile. Project Curve — Projects a B-spline curve on the surface. No boundary is created. Impose Onto — The profile curve is imposed onto the surface as a boundary (that is, a hole is cut into the surface).
Keep Profile	If on, the profile curve is retained.
Remain As Solid	If on, a trimmed solid remains as a SmartSolid. If off, a trimmed solid is converted to a SmartSurface.


Trimming a surface (orthogonal to profile). Left: Identify the surface anywhere in the region that is to be retained (1) and the cutting profile (2). Right: Accept (3) to create the hole.
