I am sure this must be possible but I can't find it as a forum question or see a simple way to do it...
To start with I just want to draw a circular arc!
I am actually trying to illustrate the tracks that would be left by a vehicle making first a 130 deg right and then a 20 deg left turn, so there would be 2 lines with concentric arcs. The actual values for the turns will result from imposing the lines on an aerial photo or plan. Any pointers would be very welcome!
