Protel 99SE, avoid autoroute certain nets

[davorin]

Evening (o;

I tried several ways that a single-sided PCB has a GND plane
and that Protel 99SE should not route GND...

Whatever I do he still routes GND although it is connected
through GND plane already.

Tried with "Classes" as GND being not a member. But it says
that the "Rule not followed by router"...

Any easy way to avoid certain nets to be routed?

I think that your problem is that you have a 2 sided board instead of a single layer board. I am not familiar with 99se but in protel_dxp you can define a net as a plane. And of course it is needed to reserve a layer for this plane.
