I have experienced the same thing - try adding a oversize value to the
clearance and it will take care of the problem. I think it's a rounding
error.
Set the clearance oversize to 1 mil or larger

Subject: [PCB_FORUM] gnd plane and drc errors
To all gurus:
I have multiple gnds (pwr,signal,earth and shield) and i need to edit all
layer, so i'll change all planes to dynamic shape and let program clear all
via that don't need to be tied. But i always get drc errors, rule says 8
mils but the opening is 7.99 mils. What gives? after i'm finish i change
shape type back to static and tie all the four types of gnds back together
around board edge. Why do i always get the 7.99 mils?
thanks in advance
Sam
