The square in you're drawing isn't square. I don't know how TurboCAD works, but if it has an ortho mode, use that, or enter the coordinated directly. Draw everything the correct size, and use the offset command (or whatever it's called) to offset everything by .0625 if that's the too radius.

Ace seems to be working fine, but make sure you add the Z value in ACE before the conversion, or you'll just be cutting air.
