I've some problems to setup a component specific pad to pad clearance.
In my design I'm using a 0.2 mm pad to pad clearance.
For a specific footprint, I must allow a smaller pad to pad distance.
I've tried to setup a rule in Pads Router.
Therefore I've selected the clearance tab under component properties.
But the distance matrix is greyed out and can not be edited.
My next attempt was to setup the rule in Pads Layout.
In the first step I've selected the according component.
In the context menu I've choosen "Show Rules".
But the clearance button is also greyed.
Is there a way to setup this pad to pad clearance rule in Pads Layout or Pads Router?
Is there perhaps a limitation that depends on the kind of license I'm using?
Or must I define this rule in Pads Logic?
(I'm afraid to go this way because I don't want to destroy my rules that I've defined in Pads Layout).
