OK - so here is part 2 of my earlier question/issue. I still think either I am missing something or something is not working right. I have a design that needs 40 mil clear between certain nets in order to pass hi-pot isolation requirements. I have always thought that conditional rules were pretty much at the top of the hierarchy and took precedence over anything else. So I set a conditional rule of 40 mil clear between class VIN and net GND_SIGNAL as shown in Conditional1.jpg. It also shows the resultant copper pour on layer 2. Not the clearance I want/was expecting. Conditional2 is almost the same thing except the "remove unused pads" box is unchecked. Now I get the clearances I need. Seems to me with 40 mil clearance specified in all the "drill" boxes it should not matter whether I remove unused pads or not. What am I missing or doing wrong?
