AutoCad 2D:: Reduce Number Of Vertex Points In Polyline Or 3DPolyline? Any way to reduce the number of vertex points in a polyline or 3d polyline and retain the basic shape but without having to redraw over the top it? Ideally, I would like any adjacent segments which are in the same direction as each other to become one segment. Free Lisp to Reduce Polyline Vertex. Reduce polyline weight lisp is developed to address this problem. You can create polyline having fewer vertices by specifying the distance at which you need vertices. This lisp command will find the point on the polyline at a multiple of specified distance and will create a new polyline, thereby reducing.

- How to simplify a complex polyline (reduce number of vertices)? If you have a complicated polyline (with hundreds or thousands of vertices) in your drawing and you want to simplify (weed) it in AutoCAD LT, you can use use the function 'Segment curve' from the add-on application 'CADstudio LT Extension'. This function replaces (with a single click) the selected arc or polyline with straight.

Weeding Factors
Use Weeding Factors to reduce the number of points generated along 3D polylines. Weeding factors ignore vertices that are closer together than the Distance factor and that deflect less than the Angle factor. A larger distance and deflection angle weeds a greater number of points. The distance factor is measured in linear units and the angle factor is measured in angular units.
Weeding Factors must be less than Supplementing Factors.
A point on the 3D polyline is weeded by calculating its location in relation to the vertices before and after it. If the length between these three points is less than the weeding length value, and the deflection angle is less than the weeding angle value, then the middle point is not added to the contour data file.
Supplementing Factors
Use Supplementing Factors to supplement or add vertices along 3D polylines. The supplementing distance is the maximum distance between vertices. If the distance between vertices on a contour is greater than the Supplementing Factors, then points are added along the contour at equal intervals that are less than or equal to the supplementing distance. The smaller the distance, the greater the number of supplemented points.

Bulge
For curves, the bulge value is a ratio of the distance from the arc to the chord divided by half the length of the chord. The bulge factor adds vertices to a polyline curve, creating an approximation of the curve using straight line segments. The length of these segments varies depending on the bulge factor and the degree of curvature.
- Run Weed Polylines individually. If you run it with other operations, it will always be run before other actions, regardless of its position in the list. In addition, it will only be run once, regardless of how many times it is listed.
- Weed Polylines is not an interactive operation. AutoCAD Map 3D makes the changes automatically during cleanup.

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.
