Presently, the clearance parameter of the route style= is only respected by polygons (I think). The "online" DRC isn= 9;t (yet) sophisticated enough to respect anything other than the global DR= C requirement.

My suggestion for a work aroun= d at the moment is to use a grid setting that places the traces at the desi= red spacing.

Having a per-net or a per-netcla= ss DRC, both online and off, is on the todo list. You're not the only p= erson to desire this feature. I have to put some infrastructure in place to= support it. I've been working on it, but progress is slow.

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 ?
