How do i create holes based on a DXF i have imported WITHOUT redrawing the polygons

Question

I have designed a panel from acrylic. It has switches, buttons, LEDs a LCD screen and back lighting. I saved the panel and then imported to brd as a dxf and use it in dimension layer for board outline etc. I need to cut out a number of holes based on the "holes" in the cad and some circles are NOT holes BUT LED positions. How do i create holes that must be cut out without drawing new polygons and trying to align to the DXF which i imported?

I hope that made sense. I need to be able to select a circle/hole and then create a hole to be cutout. Also i need to use some circles and positions for LEDs.

Thanks in advance

I thought this was an interesting query so decided to write a ULP to do this. Save the below as circleToHole.ulp.
sprintf(cmd, "GRID mil; HOLE %f (%f %f);", 2.0 * u2mil(C.radius), u2mil(C.x), u2mil(C.y));

you don't need to mess with the grid settings, just force the unit for

the values:

sprintf(cmd, "HOLE %fmil (%fmil %fmil);", 2.0 * u2mil(C.radius), u2mil(C.x), u2mil(C.y));
