I have a polyline with too many nodes, I have tried a script called 'Weeds' but it says 'not a polyline, its a LWpolyline' Is there any better way to reduce the. Find Select a polyline. Enter e (Edit vertex). The first vertex is marked with an X. Use the Next option to move the X to the vertex preceding the one that you want to delete. Enter s (Straighten). Use the Next option to move the X to the vertex immediately following the one that you want to delete. Enter g (Go). The vertex on the polyline is deleted. Can you 'simplify' a Polyline or 3. [Archive]Hi,Thanks for your replies, but so far nothing has worked. Do a search on de- densify, there has been a thread.
Just wondered if there is a 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. In my image you can see the number of points it has, the majority of which are not necessary for my needs (it was imported from a client's drawing). My desired linetype will also not show because of this. 44409 Any help appreciated. If you use the Command 'Pedit' ->Edit vertex ->Straighten, you can remove groups of vertices at once by clicking 'next' until you get to a vertex you want to keep and then select 'Go', and repeat. Unfortunately its not a quick fix, but it's faster than removing each vertex individually:P It's still a painful way of doing it though.
I'll be interested to see if anyone knows of anything that is both efficient and accurate. Personally I would just draw a Spline over the top of it and get rid of the damn thing asap:s They're much better at accepting linetypes more consistently (because polylines restart the linetype at each vertex, splines don't). Hope this is. Slightly helpful.

By definition when you remove vertices from a polyline you loose accuracy. There is a system variable called PLINEGEN that when set to 1 continues the line type style around the vertices. Hi, Thanks for your replies, but so far nothing has worked. Do a search on de-densify, there has been a thread on that recently. I think ReMark had some useful advice on the matter.
There was also a LISP routine that someone suggested. I searched 'de-densify' and 'densify' and the only topic I found was this one: Link (which I don't think is the one you were referring too. Can you please provide a link? There are a couple of LISP routines on that thread, 'weed.lsp' and another 'purge-pline' found here ((linked by Lee Mac). I tried both and here are my results. FYI, I am trying this on a 2DPolyline. Purge-Pline: Command: Simp-Pline loaded, type SPL to launch the function.
Newblue Fx Keygen Pc. Command: SPL Select les polylines to be treated or: Select objects: 0 found Select objects: 0 found, 0 total Select objects: 22 treated polyline(s). Command: I have no idea why it 'treated 22 polylines when I only tried 1, without success. I tried converting the polyline then tried the command again. Command: SPL Select les polylines to be treated or: Select objects: 1 found Select objects: 1 treated polyline(s). Command: This made no difference whatsoever, so I relaunched ACAD and tried the 'weed' LISP. Weed: Command: WEED Enter offset distance: 1 Enter leg length: 1 Delete original Polyline [Y/n]: n Select a PolyLine or Line: POLYLINE selected Checking polyline verticies.
Weed Error: bad argument type: FILE nil Command: I tried a couple of more times with both smaller and larger values but got the same result. Again, I converted the polyline before more attempts. Command: WEED Enter offset distance: 1 Enter leg length: 1 Delete original Polyline [Y/n]: n Select a PolyLine or Line: That's not a LINE or POLYLINE, it's a LWPOLYLINE Select a PolyLine or Line: Nothing Selected Select a PolyLine or Line: *Cancel* Weed Error: Function cancelled Command: So, is there anything I'm missing or doing wrong or is there anything else I can try? I have attached the offending drawing in case someone can look at it. 44420 Thanks. You first have to understand that in AutoCAD there are three types of polylines, a 3D-Polyline, a 2D-Polyline and a LW-Polyline (or just polyline).
