Do not mind. Tried to figure how to add attributes for clearance or maybe more correct named creepage as it is distance on circuit board. First reading manual page, loooking for documentation but approached the time then I needed to slop so I thought maybe better to ask on geda mailing list and it all turned around back to you.

I actually got one answer there i he refere to a link http://www.delorie.com/archives/browse.cgi?p=geda-user/2015/10/14/04:07:24 "note that you can effectively attach attributes to nets using symbols. The fine primitive gnetlist:graphical-objs-in-net-with-attrib-get-attrib (the longest name in the gnetlist namespace) allows a backend to extract them. This is more versatile, as it allows the back end not only access to attributes, but allows a symbol to define relationships between nets. Consider the following, which could allow a backend to deduce that a pair of nets is a transmission line, and give it a name:"

Worked all day long and have an hour or two left today.
