Hello Klaudio!

@You : "...I am curious, does this script has a feature where you can select one edge (or few continuous edges) and then in the script to get it's length + select all other edges with the same length? It would be handy to have that option to get it like that instead of tweaking min and max slider until you get the right edge. Do you know what i mean?"

Yes, I mean.
No, actually there isn't a feature like that because I've stopped the developing of that plugin some times ago because I'm very busy at work and I can't put again my hands on it.

But...maybe also the actual implementation of my custom command can easily allow you to achieve what you want to do.

Follow this little video tutorial based on your model : http://take.ms/BN9QV

I often use the that trick. I hope the it can be useful also for you.

Ciao!
