public interface IDwgExtrusionable

All dwg drawing entities that need to compute an extrussion before draw them must implement this interface. This "extrusion" transforms coordinates from the "Object Coordinate System" (OCS) to the "World Coordinate System" (WCS). For some entities, the OCS is equivalent to the WCS and all points are expressed in World coordinates. Entities Notes 3D entities such as These entities do not lie in a line, point, 3dface, particular plane. All points are 3D polyline, expressed in world coordinates. 3D vertex, 3D mesh, Of these entities, only lines and points can be extruded. 3D mesh vertex 2D entities such as circle, arc, These entities are planar in nature. solid, trace, text, attrib, attdef, All points are expressed in object coordinates. shape, insert, 2D polyline, 2D vertex, All of these entities can be extruded. lwpolyline, hatch, image
