You can use ActiveX to query and edit LoftedSurface entities in AutoCAD drawings. You cannot create a LoftedSurface object with ActiveX. A lofted surface is created in AutoCAD by drawing a solid or surface through a set of two or more cross-section curves. The cross sections define the profile (shape) of the resulting solid or surface. Cross sections (generally, curves or lines) can be open (for example, an arc) or closed (for example, a circle).
