Thanks for going to the limit of your english! ;-)

Yes, i played with the BrepNameSubObjects node - its very interesting and studying how you programed it brings me to the limits of my Javascript...
But there must be a simpler way to just get a edge of a object...
Unfortunatly my objects2 extension doesnt have the ExtractEdges node... i am outdated:-{ and i cant run your select-extract.nod example.
But i think that node can be the solution to me simple problem..

First i have to search for the latest object2.js ...
