Curves are cubic or linear NURBS. You cannot render them, but you can use them for various purposes in Softimage. You can:
• Draw and manipulate curves directly in the 3D views. See Drawing and Manipulating Curves.
• Modify the curve in a variety of ways. See Modifying Curves.
• Create curves from other objects in your scene. See Creating Curves from Other Objects.
• Import EPS files containing curves. See Importing EPS Files.
In addition to these procedures, you can also get primitive curves and text (as described in Starting From Scratch: Primitives and Text [Modeling and Deformation Basics]) or import models and scenes with curves (as described in Importing and Exporting [Data Management]).
