Description

Creates NURBS surfaces by interpolating a group of cross-section curves. The nurbs curves are lofted in the order in which they were added to the group.

FUNCTION CreateLoftSurfaces(
               groupCurvesHd   :HANDLE;
               bRule           :BOOLEAN;
               bClose          :BOOLEAN;
               bSolid          :BOOLEAN) : HANDLE;

def vs.CreateLoftSurfaces(groupCurvesHd, bRule, bClose, bSolid):
    return HANDLE

Parameters

groupCurvesHd		HANDLE
bRule		BOOLEAN
bClose		BOOLEAN
bSolid		BOOLEAN
