Kent Cooper used an older tip (Cadalyst CAD Tip No. 963) as inspiration for this new and improved version. This AutoCAD routine will correctly divide an ellipse in just the right way to reflect the axonometric-projection equivalents of equally spaced locations around the circle that the ellipse is a projection of. Start by loading the LISP file, then type in the command DE. The routine will divide ellipses of any axis ratio, and works on partial ellipses (elliptical arcs) as well as full (closed) ones. See the comments in the LISP file for additional notes. As always, Kent's code is well written and heavily commented. |
