Not quite. The ``internal resolution'' would be the same, but the
visible units (on the gui and in the exports) would be scaled by
the scale factor, on a per-.pcb basis.
If I understand correctly, this would not solve the problem. The
problem results from working with data in metric format which can not
be represented exactly using an inch based internal integer. If the
internal representation is metric, then inches can be represented exactly.
Are you suggesting that 32 bit integers representing nm could be used
and the 2/4 meter limitation could be resolved by using a scale factor?
Am I up to speed now?
Personally, I can't imagine a PCB larger than 2 meters much less 4
meters. Or is the possibility of uses other than PCB design being
considered here?
