Simulation of a field hospital

Hello! I need to build a similar pavilion structure from grids and a tubular frame, but unfortunately I can’t do it, because I recently started studying grasshopper and don’t quite understand some of the subtleties. I attach two project files and an analog of the pavilion, which I am focusing on, to the discussion. Please help, who has the opportunity to build such a pavilion or explain how it can be done?
I get it like this

As a result, I need this design
