Hardscape paths

[Marietta]

Help

I am trying to create paths using hardscape directly or by creating a polyline first and then converting. I keep getting the following error message:

Problem creating pathway hardscape

The pathway hardscape could not be created because it is self intersecting.

Sometimes when I create the pathway directly from hardscape, it works, but if I try to modify it I get this message. When this happens, I either have to redraw the path or draw a new polyline to convert from.
