Splitting or Trimming NURBS Surfaces

The Project tool projects a 2D object or NURBS curve onto a NURBS surface, and then splits the NURBS surface or trims the NURBS surface according to the region selected. This allows nonlinear splitting or trimming of surfaces to create different shapes or cut a hole in an object.

Mode
Description

Split

Splits a NURBS surface with a projection

Trim

Trims a NURBS surface with a projection

Add

Adds a projection to a NURBS surface

Add Upward

In Add mode, adds the projection in the profile plane normal direction

Add Downward

In Add mode, adds the projection in the opposite direction from the profile plane normal direction

Add Both Directions

In Add mode, adds the projection in both the profile plane normal direction and the opposite direction
