Bill pointed out a robust method that works for flyers with limited resources. For almost all the "Indoorists" I know this is a 30 second task in a CAD program.

Does anyone here remember the "beam compass", or am I the only Flintstone left? The arcs should simply be specified by their radius, not percentages, and if you don't have a real professional K&E beam compass, it's probably the easiest tool in the world to whip up from shop scraps (a strip of wood, a pin and a sharp pencil).
