-enables importing/exporting objects directly to/from the 3D document, but
-doesn't handle the SVG output from the Drawing and TechDraw modules.
-
-Currently it only reads the following entities:
-* paths, lines, circular arcs, rects, circles, ellipses, polygons, polylines.
-
-Currently unsupported:
-* use, image.
