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)?
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.

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.

Please see image here:
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.

While we are much more focusing on AutoCAD basics here, it is necessary to learn how you can convert LINE to Polyline and vice versa.
This might not make sense to you now now, but will surely come in handy when you will come to a point where you need to convert a line to a polyline. An example where this will be needed is when you are working on a project where you need to join a series of line to make it a single object and use the resulting polyline as a PATH.
A concrete example:
Let’s say we need to create an ARRAYPATH in AutoCAD, if we create our path using the LINE command, the path will be made of many line segments, To use this command you need to have all lines converted to a single object. You will then need to convert Line to Polyline.
What is a Polyline (PLINE command)?
In AutoCAD, a Polyline is a single object that is composed of lines and/or arc segments.
How is a LINE different from a Polyline?
A Polyline is made of LINEs. It is not possible to select a segment of a Polyline without selecting the whole.
