Polyline mass edit

miikka1978

Is there a plugin that can edit (add control points) multiple polylines at the same time?

I would need to add more control points (nodes)evenly with certain spacing to my contours without removing the original control points. Also, it would be essential to do it for multiple polylines at the same time so that there would be no need to do this individually for each line. If I remember correct, simplify contours makes the opposite function, reduces control points, for multiple polylines at the same time.

You might give my Spline Fit plugin on my blog a try.

Curvizard by Fredo6 ?

i think it might be helpful if you attach a .skp to a post here so we can see more of what you mean by 'control points' or 'nodes' ... i can't really tell if you're talking about actual control points or vertices or what..

there are fredo plugins which can accomplish this stuff -- depending on how i interpret your questions..
so a model with an example or two of a before&after curve would be helpful.

Here is what I am looking for, see below. Basically I would like to modify my contours so that I could add more line segments into the straight parts. This would be essential when creating terrain mesh.

in that situation, i'd think it might be best if you have BezierSpline installed:

if you weld all the various pieces of the curve then right click on it and choose:
BZ-convert to -> Polyline Divider

you then can enter the spacing you'd like in between each vertex and the curve will be divided evenly..

that said, you can't do multiple curves at one time using this method.

Thanks for all the suggestions. I will need to check Spline Fit plugin and Curvizard. Sorry for not being 100% clear with my explanation, I agree that I should have had picture in the beginning to explain the matter.

Actually, I did some testing with Curvizard and I didn't find a way to add segments to straight parts without affecting the round parts. When using poly divider function I get more segments in straight parts part but I lose the multiple segment in round parts, and therefore I lose the original form of the contour.
