I tried cutting 2 holes on a sheetmetal part and doing a circular pattern in the un-flattened state.

The holes worked fine, however when I flatten the part I can't dimension the hole diameters or spacing. They are elliptical.

I tried flattening the part and then adding the holes but when I un-flatten the holes disappear.

How can I get holes that I can dimension in this part?

Regards,
