CreateLoftSurfaces

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

Name Type Description
groupCurvesHd HANDLE
bRule BOOLEAN
bClose BOOLEAN
bSolid BOOLEAN
