polyop.cutVert <Poly poly> <int start_vert> <point3 destination> <point3 projdir> \
node:<node=unsupplied>

If <poly> is a node, or if <poly> is an Editable Poly and <node> is specified, <destination> and <projdir> are in the current coordinate system context.

If <poly> is an Editable Poly and <node> is not specified, <destination> and <projdir> are in the poly's local coordinate system.

Returns the index of the new vertex if created, or undefined if no vertex is created.

polyop.cutFace <Poly poly> <int face> <point3 start> <point3 destination> <point3 projdir> \
node:<node=unsupplied>

If <poly> is a node, or if <poly> is an Editable Poly and <node> is specified, <start>, <destination>, and <projdir> are in the current coordinate system context.

If <poly> is an Editable Poly and <node> is not specified, <start>, <destination>, and <projdir> are in the poly's local coordinate system.

Returns the index of the new vertex if created, or undefined if no vertex is created.

polyop.cutEdge <Poly poly> <int edge1> <float prop1> <int edge2> \
<float prop2><point3 projdir> node:<node=unsupplied>

If <poly> is a node, or if <poly> is an Editable Poly and <node> is specified, <projdir> is in the current coordinate system context.

If <poly> is an Editable Poly and <node> is not specified, <projdir> is in the poly's local coordinate system.

Returns the index of the new vertex if created, or undefined if no vertex is created.
