The Decompose command can decompose NURBS surfaces, 2D polygons, 2D polylines, 3D NURBS curves created with the Compose command, and open 3D polygons.
Occasionally, surface creation methods like the Create Surface from Curves command can create a surface with internal discontinuities. Many of the 3D Power Pack tools and commands are not designed to work with these types of surfaces. The Decompose command can separate the surface into NURBS surfaces without discontinuities.
To decompose a NURBS surface or object into individual segments:
Select the NURBS surface or object to be decomposed.
Select Modify > Decompose.
The NURBS surface is separated into individual surfaces, or the object is separated into individual segments.
