Data Structures
class	Geom_SurfaceOfLinearExtrusion
	Describes a surface of linear extrusion ("extruded <br> surface"), e.g. a generalized cylinder. Such a surface is obtained by sweeping a curve (called the "extruded <br> curve" or "basis") in a given direction (referred to as the "direction of extrusion" and defined by a unit vector). The u parameter is along the extruded curve. The v parameter is along the direction of extrusion. The parameter range for the u parameter is defined by the reference curve. The parameter range for the v parameter is ] - infinity, + infinity [. The position of the curve gives the origin of the v parameter. The surface is "CN" in the v parametric direction. The form of a surface of linear extrusion is generally a ruled surface (GeomAbs_RuledForm). It can be: a cylindrical surface, if the extruded curve is a circle, or a trimmed circle, with an axis parallel to the direction of extrusion (GeomAbs_CylindricalForm), or a planar surface, if the extruded curve is a line (GeomAbs_PlanarForm). Note: The surface of extrusion is built from a copy of the original basis curve, so the original curve is not modified when the surface is modified. Warning Degenerate surfaces are not detected. A degenerate surface is obtained, for example, when the extruded curve is a line and the direction of extrusion is parallel to that line. More...
