I'm trying to get signal lines from a LQFP100_14.fp footprint out 
to everywhere else (small.sch / small.pcb [1] if you are curios).

So I'm looking at grid sizes and route styles.
[2] tells me that for 35um, a line width and isolation of 125um is
the minimum, so I think thickness 0.15, keepaway 0.15 would be find.

Drawing a line and surrund it with copper (F5 rectangle) i get the req. 
0.15mm keepaway. How do I make two parallell lines to have the same 
separation, if I draw a line and then another one as close as possible
with "Auto enforce DRC clearance" the separation will be what is set
in the DRC line in the file. Isn't there a way to draw lines so that
the keepaway (for that route style) is respected ?
