Draw a polyline over another polyline

[Gustavo]

Hello People,

 

there are a way to draw a polyline over a segment of another polyline? I would like to draw a polyline of a vertex X until vertex Y and then go to another direction. I think that a way to copy only a segment without explode all the polyline will work too.

 

Thanks.

I presume you mean without having to follow the polyline segments one by one, snapping to each vertex, etc.

 

If it's one or two segments, then I'd just snap to the vertices and draw on top of the existing polyline.

 

But if I had a 4000 segment polyline and I needed to redraw 1000 segments, I'd copy the polyline in place, then break it at segment 1000, and erase the portion I don't need.

 

I want to say ToolPac had some sort of "polyline follow" tool, but I could be mistaken and thinking of somewhere else I've seen that.

You can use this without the offset operation - simply comment/remove lines 131, 132 & 133.
