Use this command to find where a graphic intersects itself, which may be hard to tell sometimes. The program will highlight and zoom into the areas that have self-intersecting loops, which you can then remove with the Vector Edit tool.

The most common self-intersecting loops happen with Bezier curves, and this can cause various unwanted results in PowerFlow, such as lack of a guide path and wrong loop directions. Running this tool will show you where these problems are so you can fix them.

Here is an example of a self-intersecting loop. The control points for the Bezier curve need to be reversed, or rotated 180 degrees.
