Trimmed Surface

What is it about?

This page covers the Trimmed Surface object in Cinema 4D. It represents the spline-bounded surfaces of imported IGES CAD files — keeping trimmed NURBS patches editable as distinct objects in the Object Manager.

IGES-supported files are comprised of spline curves and spline surfaces. These objects are the foundation for the trimmed surfaces. Each object can be seen in the Object Manager.
