This is BobCAD. I did it in 2d. But it is prolly easier in 3d. I set the stock so it is at a 45° angle to the machine. Then I pick the 2 point farthest to the let in the x axis. Set them to drill .050 moved over .125 to the center point set it to drill .100 then moved over to the next set of point drilling the at .2 and increasing .100 every time I step in the x direction witch is the direction the 45 is in. Sorry if I'm not very good at explaining this.
