I was wondering could someone help me out.
I'm trying to find out what the Trig formula for calculating a bolt hole pattern for a given radius and a specific # of holes.
I want to create a set of variables so the user inputs the arc radius and number of holes req'd. And then it plots the centers accordingly.
I'm actually using this in another application for our cnc router with a pgm called woodwop 5.0
I'm just not sure what the equations should be set up like to do something like this. Any help would be greatly appreciated.
Thanks in advance
Brad
