Title: Simplifying - Polylines
Post by: MSTG007 on July 17, 2017, 08:53:05 AM: Guys,

I am trying to find a quick way to reduce / simplify polylines. I have tried a lot of different lisp's but have not found one that can do arcs that well. I know I can always retrace it, but when there is ALOT; its a pain.

Thanks for any ideas on this!

I would go with Simplify Objects, and select Create Arcs. You will have to play with the Tolerance valve to weed the vertices. The help file is explains the command nicely.

Some lisp files on this thread might also be of help.
