NURBS
When you import an IGES file into the software, IGES meshes are converted
to
NURBS on page 2152 surfaces, rather than to 3ds Max mesh objects. An IGES
file with multiple meshes imports as a single NURBS model. Each IGES mesh
is a surface sub-object within the model.
Each surface sub-object based on an IGES mesh is initially a
rigid surface on
page 2172 . To edit the surface and its
CVs on page 7750 , you must first make
the rigid surface independent. The following procedure explains how to do
this.
Future Compatibility
The group that maintains and updates the IGES standard, the IGES/PDES
(Product Data Exchange Standard) consortium, attempts to keep IGES upwardly
compatible. It's likely that files generated by the software will be compatible
with future versions of IGES.

Procedures
To make rigid imported NURBS surfaces independent:
1 Select the object.
2
Go to the Modify panel.
3 In the Modifier Stack rollout, choose Surface as the sub-object level.
4 Select the surface sub-object you want to edit.
5 In the Surface Common rollout, click Make Independent.
