Non-hole drilled when selecting flat area

[KMoffett]

I created a plate with two 3x4 arrays of holes in AD Expert 2012 (14,0,4,14056 / 32-bit). In Standard CAM 2.0.069 I set up a drilling operation. In Plate1.AD_PRT, I chose "Select holes on flat area" and selected the face of the plate. In Plate2.AD_PRT, I chose "Select drill points/circles" and selected Sketch 2 and Sketch3. Plate2 drilled the 24 holes in the correct locations. In Plate1, it drilled one extra hole in the center of the plate, where I have no hole.

Why?

When using "select holes on flat area" Alibre CAM drills all the holes PLUS 1 hole in the center of the flat area boundary. When using flat area, check "Use dia. filter" set the min dia slightly under the hole size and the max dia slightly larger than the largest hole. Note:I think if you copy the Mop you must re-set the min and max filter again.

Works perfectly. Thanks!

Thanks David, and Udane (sic spelling) at tech support for explaining what was happening. It makes perfect sense and fixing all my parts will be sooo easy.
