Hmm… so here’s my go… Have a play and see if it works for you?
I don’t think you can extract a bounding box from a section (and anyway it would be axis aligned?)
I also don’t think you can extract the ‘location’ to get the coordinate system.
So my solution is a geometric one, to get (what I think you’re wanting) as outputs… I got the crop box and extruded it by the view depth, it seems to work even if the section has crop view unchecked.
Hope that’s of interest,
Mark
Edit: You’ll need the MEPover package
