The SURFACE menu holds commands for creating and handling of surfaces.
When creating new surfaces, the representation of the surface is automatically determined by the type of curves with which the surface was created. Much like curve objects, there are three different representations for surfaces: faceted models, B-spline surfaces and Bézier surfaces.
The surface manipulation commands work automatically according to the representation of the surface. For example, the command Surface:DesignÞEdit always leads to the edit mode appropriate for the selected surface.
The curves that define the surface must be defined in different curve sets (projection and section sets) in the same element.
