Thanks for the quick reply.

I see that I can select all components manually on the board and then execute the ChangeClearSize() command (and I've been doing that), but I was wondering if it's possible to propagate the change to the 0805 footprint file to *all* 0805 components in the layout.  Perhaps from the command line.  i.e. something that amounts to a smart search-and-replace for all Pad[] entries in an Element[] entry that has the Description "0805".

Also, re: best practices for making footprints -- is there an advantage to specifying clearance=0 vs. clearance=non-zero?

Thanks as always,
James
