You'd like to know how to simplify polylines with a huge number of vertices. In the example below, the object on the right contains many vertices. You want to reduce the number while maintaining the original shape so that it becomes the one on the left. Hello everyone. I was wondering if there is a way or a lisp command that reduces vertices of curved polylines. When i say a 'curved polyline' i mean a polyline that has two segments that are arcs with the same radius, and if i explode that polyline and join it again, those two or more segments/arcs, just become one. I have a polyline (lines only) which has about 500 points in it. I would like to reduce the number of points in it. How can I do it in AutoCAD? (or may be some other application)?

Quickbooks pos 2013 update download. P.S. Polylines were made of splines converted into set of lines. But the level of detail is too high I want to decrease it.

Here's one of the LISP routines in AutoCAD forum: Reduce Polyline Points. Here's the result after running the LISP routine. Products: AutoCAD Products. Hi all, Here I have a problem our client asked to ensure that a single polyline should not contain more than 1000 vertices for further work he will carry on vector data. But i donot know how I can check no of Vertices. Thanks in Advance, snviswanadha. Reduce the # of vertices in a polyline - again - posted in GIS: I have seen discussion about reducing the number of vertices in a polyline and the suggestions usually are to generalize by simplifying or smoothing via ToolboxGeneralization. That does not reduce the number of vertices. It only reshapes the lines (all polylines in the selected shapefile by the way).

This LISP script does the job. Create an LSP file and add it to AutoCAD, then use PLD command to run it.

I wrote a utility call Reduce that does this. It is a compiled Autolisp fas file, which is run like a normal lsp file. You can download it here https://www.theswamp.org/index.php?topic=27724.0.

The lisp routine may be the best deal for you, but I use the overkill command to remove points from polylines (when the command is active, go to settings). It is an express tool that is usually used to remove duplicate lines but it works to optimize polylines. The one thing you need to be careful of is when your polyline has a width. Overkill will usually kill widths.
Cheers.

I have had this problem to and I usually just explode the polyline, then do an overkill and then join the remaining lines. I have 2014 LT so lisp routines wouldn't work for me. It was the only way that I could do it.

If you have rhino, 'SimplifyCrv' works pretty well. Not sure how it functions, but I had a similar problem, and this command was able to lower the number of control points in a polyline beyond commands that come loaded with autoCAD.

This is a very good utility for PLine to reduce file size. But in above case, if 2 green points was deleted, the PLine become sharp (not tangent). Please consider about it.
