Getting dimensions of panels from Curtains which are being cut by mass

I’m looking into obtaining dimensions from curtain panels that are cut by mass.
So far I’ve been able to extract edges which contains edges from many different solids.

This what I’m looking for:

Anyone have any ideas, how I can extract this?

Are you looking to only get the “glass” part or the entire geometry.
This will proove more complex but still doable

Here’s an idea

Thanks @Daniel_Hurtubise for this.

This is part of what I was aiming for; eventually, I’ll try to extract glass.
