Autocad Remove Vertices From Polyline

Issue:

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.

Reduce Vertices In Polyline

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. Oct 23, 2013  By Virupaksha Aithal Below code shows the procedure to remove the user specified vertex of AutoCAD 3d Polyline. Code, first traverse through the vertices of the user selected 3d Polyline and prepares a list of vertexes to be erased. CommandMethod('Remove3DVertex') static public void RemoveVertex Document doc = Application.DocumentManager.MdiActiveDocument; Database.

Solution:

  • Remove vertex from Polyline. Hi All, Is there any way to remove from Straight Polyline unwanted vertices. I have so many Polylines like this Please guide me and suggest. For ex: cyan Color marks are nodes Red Color mark Vertex are need to remove Green Color Vertex is important need to keep.
  • Click Home tabModify panelEdit Polyline. 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.
  • Jul 13, 2006  I'm working in AutoCAD 2004. I have a drawing from another company with what are supposed to be lots contour lines. Before I received it someone turned the contour splines into polylines and then exploded them, leaving each 'contour' on the correct elevation, but made up of hundreds (and hundreds!) of tiny line segments. I need to turn these back into polylines and then remove vertices.

Remove Vertex From Polyline In Autocad

Autocad Remove Vertices From PolylineThere isn't a straight-forward command to simplify such complex polylines. The process is called 'weeding' and there are several custom LISPs which can achieve this. Here's one of the LISP routines in AutoCAD forum: Reduce Polyline Points

Here's the result after running the LISP routine.

I need to turn these back into polylines and then remove vertices. Getting them into polylines with the pedit command is very time consuming, does anyone have an idea to streamline this task? Also, I have been unable to find a lisp routine that will remove vertices in V2004...any suggestions? Thanks!
