The OP requested 90 degree paths.
Cutter compensation has nothing to do with it. Cutter compensation is simply offsetting the tool to the left or right (or up or down for a horizontal path) from the programmed path.
CAD programs like inventor cannot duplicate the proper shape with a simple sweep because the profile for the sweep is 2d and set to follow the path so when it gets to a corner it locks the inside edge of the profile and revolves the profile 90 degrees. This is NOT real world. What I posted IS correct and the only shape a ball end mill will make when programmed to do a right angle path.
Why the other program that JD used did not show the correct path makes me think that even though he swept what looks to be a 3d profile I believe the program is still taking a 2d shape from that 3d "tool" and sweeping it identical to how Inventor does it. I would be curious to see if he didn't do a rectangle path and stopped the tool in the middle of the part will it leave a rounded shape at the end or square like inventor will.
