Quadrant Snap locates points at the 45°, 135°, 225°, and 315° angle points based on your point selection. This function is for use inside AutoCAD commands. To use this utility, load the LISP code and type (QS) when one of AutoCAD's commands is waiting for a point input. When (QS) runs, you will be asked to select the quadrant of an arc or a circle. The point you select is used to determine which quadrant was picked and is then reset to match the exact halfway point of the quadrant. You might consider modifying this routine to work inside other functions of your own design. John, thanks for a great example of how to use LISP to make AutoCAD work the way you want.
