[/QUOTE]Have you see this routine in this page:http://newsline.cadalyst.com/code/browseyear.cfm?fullyear=2003#9
Best/easiest way would be a lisp routine as in the link Arben posted.
Flatten would not help you much anyway; it would change all z values to 0 but would still be a 3d polyline, not responsive to CONVERTPOLY.
However you could explode the flattened 3dpoly, use pedit or mpedit to join back to a lwpolyline.
You should be able to install Express Tools off the original installation disk, so you would have the Flatten command.
