that you create in 3ds Max or import from other
MAX files.
Note: This modifier is similar to the Extrude
modifier in that once the Sweep is applied to a
spline, the end result is a 3D mesh object. Both

multiple NURBS curves.
This modifier is very useful for creat ing structural
steel details, molding details, or in any situation
where you need to extrude a sect ion along a spline.
