Creating surfaces using 3D curves
3D curves may be required to define new boundaries for surface creation.
For example, you could reduce the complexity of a single complex face by building it with many faces.
To create 3D curves, in the Modeling application, use the commands on the Curve tab and the options in the Curve group.
