But at least it should help you see what your automatic > layout generator is generating. the 'pc' continues to exist because it is on the active plane (while the 'pm12c' replaces in the 'm2c' on the metal1 plane). there seems to be no way to remove the 'pc' without also removing the 'pm12c', since the nature of the (3 layer contact) 'pm12c' is that, if you erase poly (or 'pc') under it, you change it into an m2c. thus, the old tricks to erase stuff: paint pc pm12c space also removes the pm12c. /jeff
