Eileen if I understand correctly
You have to create group A to be a Class
(bring up Drc Dialog box and select the Class button, then Assign a Class
name, and last select the nets you want to included in that Class name).
there fore you may set the clearance from a class to be 120 mils clearance
to X shape (trace, pads, etc)
the rest will use the default DRC settings, I assumed. that is what you want
or the other way around.

Subject: [DC] Some questions on Pads Powerpcb


Hi all pads user out there, will like to check regarding the setting on
Design rules.
I need to set 2 different set of rules for 2 different group on nets.
For first set of nets that I have group them together ( group A - consist of
20 nets ), for example i set their clearance within the group to be 20 mils.
For the remaining nets, I need their clearance to group A to be 120 mils.
How do I come about doing it  to make sure nets in group A itself to have 20
mils clearance and to the rest of the nets to have 120 mils clearance.
Tia
