Sorry...didn't think about the differences in versions.

I did find a way to do the job using the Virtual Segment tool.

The VS tool simply removes a segment of a line or curve between intersections with another line or curve. It's a fantastic tool!

I made a copy of the circle & state, and put a red outline on them (leaving the original image with a black outline). Once I had deleted the appropriate segments in each image, I superimposed them...giving the appearance of an uninterrupted line turning from black to red.

This may not be the best way, but it got my project done this afternoon.
