In Autocad, create a "point" at the center of the hole. In Sheetcam, select "Use points for drilling" in the drawing options pop-up window, when opening the dxf file.

You'll have to put the points and circles on different layers, or exclude the circles from the dxf file. If not Sheetcam will pierce the point and then cut the hole.

thanks i will give it a try!
