Polyline overlaps itself when converting to P Solid

[moak]

I was having an issue trying to convert a polyline to a p-solid. I got an error message saying the polyline overlaps itself and the psolid may not look right in 3D or elevations. The polyline was converted from a spline originally and underwent a few concentric edits.
I discovered a solution. After attempting to find the offending overlap by selecting nodes and dragging them around I had an idea. I made a large rectangular polyline and performed a "Polyline Intersection" that retained the shape of the wanted polyline. This eliminated the overlap issue. Below is an image of the solution.
I'm posting this so this thread will be here when someone else has this problem and does a search.

Please send it in to support so they can fix it.

Perry,

I'm not sure it would necessarily be a bug, especially if it involved concentrically editing.
When concentrically editing a polyline, you can get a situation where the sections of the polyline can go "negative" - or "overlaps itself".
It's really a geometric thing to do with the concentric editing.
Wouldn't hurt to run it by support though.

This was my assumption. I just wanted to share the easy fix.
I no longer have the offending object in the plan so I dont think I could sent it in. If I have a moment I'll try to recreate it.

Kevin,

A great bit of thinking to come up with the fix - I like it.
