Re: [PATCH] Math expression support for pad editor.



I have tested the patch and I really like this feature. This automatic
variable assignment will sure come in handy.
How about adding a kind of scratch pad (a single line should do) to the
footprint editor so that one can add variables (measurements) given in
Like "c1=2.9; e=0.635" in the scratch pad and then in PosX field: "-c1/2 "
and PosY: "-1.5*e" in order to place the first pad.
