PolyLine library

[Marcus]

Hi, yes it's treating each lap as a separate path, which I guess is how it's designed to work. In the absence of a change to the code (which I can't think of), the impact can be lessened if we join the path in one of the straighter parts, rather than a curve. ...

Your solution solved my problem, thank you, Kevin 
You are genius.

Glad you could work around it! But I'll modify the library to support closed paths when I get the time.
