Hi, some days ago I have received a mail with the message that you find in the attached image.
Unfortunately changing from mils to mm, creates annoying errors in the DRC. This can happen, in to modify a board, that require symbols placed in mm.
I think that Cadence can resolve the thing, and to do better also !Please Cadence correct the thing, so that the competitors must keep silent !
I have forwarded this request also to the Cadence Local Partner.
