Select rectangular duct

Hi everybody,

I looked for a solution but couldn’t find anything.

What I want to do looks simple : I just would like to select rectangular duct, join the same ducts, and get width, height and length.

But I can’t find a way to do those kind of selection.

Thanks for your help,

This should get you started
