Gene, I sent you a private email with a program attached. I took John's code and spiffed it up a little to make the overall X and Y dimensions, the corner radius and the feed all variables at the top of the program. All you have to do is edit those four variables and you can define any rectangle

Hi Gene. I have had a similar problem to what you are seeing on a mill. It turned out to be an issue with the tool table I was using. Somehow I fat fingered something and ended up with an extra entry in the table unrelated to tool diameter or length offset. Cleared that out and everything start

Gene, If you open up Arc Buddy or Arc Generator if you have the latest one and enter some start and end angles and note the I and J for the arc in that quadrant. From 0° to 270° in the CW direction I is -radius and J is 0. From 90° to 0° in the CW direction I is 0 and J is -radius From 180°
