How to remove copper pours and change clearance values?

Hi, I'm quite new to PADS and I've designed a board with only two layers (top and bottom).


1) I'm attempting to do a copper pour on the top that acts as a ground plane. Some of the pads on the top layer have 100V so I would like to make sure that I have the proper clearance between the ground plane and the pads to prevent arcing. When I change the clearance values in the Design Rules, it seems that all pads (including the ground pads) on the components adjust to that clearance. I only want the non-ground pads to follow this clearance rule. Any suggestions?


2) How do I remporarily remove my copper pour so that I can make changes to my traces and then repour?


3) How do I remove thermals from some pads on my board but not others?


Thank you,
