TYPE: SOP
TITLE: Carve SOP

Carve works with any NURBS, Bezier or polygonal surface or face.  
It can be used to slice a primitive based on parametric values, cut it into
multiple sections, extract points from it, or extract cross-sections and
curves-on-surface (i.e. profiles) if the primitive is a surface.

A surface cut with Carve does not become a trimmed surface. The parts no longer
visible are literally removed from the surface.

Note:  All U/V locations are mapped between 0 and 1.

Parameters
    Group         - Specifies a subset of primitives to carve.
    First U       - Starting location in the U direction.           /domainu1
    Second U      - Ending location for the operation.              /domainu2
    U Divisions   - Number of cuts/extracts to be performed.        /divsu
    Cut At All Internal U Breakpoints - Cut only at ends or along all
                                        internal breakpoints.		
					Only At Breakpoints must be toggled.
    First V       - Starting location in the V direction.           /domainv1
    Second V      - Ending location for the operation.              /domainv2
    V Divisions   - Number of cuts/extracts to be performed.        /divsv
    Cut At All Internal V Breakpoints - Cut only at ends or along all
					internal breakpoints.		
					Only At Breakpoints must be toggled.

    Cut           - Splits primitive at locations specified above.
    Keep Inside   - Keeps the primitives between First and Second U.
    Keep Outside  - Keeps the primitives outside First and Second U.

    Extract       - Extracts points, cross-sections, or curves-on-surface
                    along each location specified above.
                    Only points can be extracted from a face and the V
                    parameter has no effect. Extraction of cross-sections and
                    curves-on surface is possible only if the primitive is a
                    surface.
    Keep Original - Will keep the original primitive from being removed.
    Only At Breakpoints - Perform the operation only at breakpoints for NURBS
                          and Bezier surfaces or faces and at vertices for 
                          polygonal faces and surfaces.
