Note that the construction of a skinned surface is not unique.
Different constructions provides different skinned surfaces.
The given curves describe the shape of the desired surface, and hence are called profile curves . Since a skinned surface contains all of its profile curves, it interpolates the given profile curves. To design a skinned surface, select Advanced Features followed by Cross Sectional Design . This will bring up the curve system. In the curve system, design the profile curve in the desired order and make the first curve to be the current curve .
