Attribute definitions:

SweptCurve	:	The curve to be swept in defining the surface. The curve is defined as a profile within the position coordinate system.
Position	:	Position coordinate system for the placement of the profile within the xy plane of the axis placement.
Dim	:	The space dimensionality of this class, derived from the dimensionality of the Position.
