Hi guys,
I am trying to get beam boundaries as polygons using CAD file. Beam curves are open curves, there are only two curves and I haven’t been able to isolate their shapes. How can I extrude beams with their appropriate thickness/height using attached CAD File? Any help is welcomed.

I really thought that once I’d get the graph of the beams (or something really close to that) then the solution would be kind-of obvious
but now that I got something similar to the graph of the beams, I’m realizing it’s not that obvious 
still squeezing my mind on this… maybe it’s not the right starting point
thanks @inno taking your time to look into it. I though about a more geometric approach.
But I couldn’t achieve the first step. So I am stuck 
this might be one way of doing it, but there’s a majour drawback: it only recognizes beams that are composed by the very same amount of lines on each side
for instance, this beam A to B is composed by 1 line on one side, and by 3 lines on the opposite side:
but in most other cases it works, and was funny to do
Nice solution. It looks like the last few percent need to be done manually – which isn’t the end of the world.
Looks like the architect was inspired by Sid the Sloth.
hi inno,
thanks for taking your time to look into it. when i try your script, I get the following result. Is that because you used some custom package that is not installed in my device or something else?
yes, I’m sorry, had forgot to flatten something before attaching the file
here is the “right-ish” one

just a note, there is a double line here on A, and a polyline here on B that I have deleted from the original DWG (you can even just change their layers so they won’t be referenced) because they were causing some troubles:
A:
B:
You can pair with their middle points, then blue indicates lines that need to be fixed manually.

this is beautiful
