It's the "auto-added thermals" part that's tricky - there's no flag to
say that a thermal is auto-added.
But auto-redoing *all* auto-thermals might work, yes.
If you remove *all* the thermals, you lose track of which net each
polygon is supposed to connect to. I suppose you could store that

Ah. The thermals themselves don't have such flags; the vias would,
but you wouldn't want to flag a hand-placed via just because it has an
automatic thermal on it.

Sorry for the mis-phrasing, when a thermal is auto added, please set

The footprint in the lower right
jcl,
I have made this the size of 0603 parts so that i can solder ball
them, or stuff them with an 0603 resistor.
Could we make a copper shorted version as well?
It allows for the reverse of the idea, by default it is connects two
nets that an exacto can cut out.

Actually, it has a LOT of flags, including that one. I'm only
mentioning the ones that are relevent to figuring out thermals.

You can combine four rounded pads and a square one to form each half

You might look at JMP_SMD.fp in my section of gedasymbols. These jumpers

If you want a test board, I can probably etch one tomorrow and mail it
to you. Just send me a .pcb file. Or a postscript file, if you want
to try semicircles also.

The round pad with split "affords" bridging. Two square pads don't quite
have the same effect. Too bad PCB can't make the semi-circular pads!

I'm sure you have a reason for using special pads, but I'd just use some
SMT resistor footprint. I've made 3-pad strappin
In Eagle there are a couple of solder-jumper footprints. To jumper between pads
you create a solder bridge. The two pad jumper looks like two half
circles with a
gap in between. The three pad jumper consists of a half circle on each
end with a rectangular pad in between.

Each trace has a flag that says if it connects to polygons or not.
Lots of flags! Read const.h or the doc

Each pin/via has a set of flags, one for each layer, that says if it
should have a thermal, and what type.
In addition, apparently, each rat line has a flag that say
