Wireframe Advancement/ plugin

As ive found, blender has an awesome new plugin which allows you to make edges into a solid frame like structure. I’ve been playing about with it in my student architectural project and so far have come up with this:

I was wondering though if anyone was able to help me out with extending this feature. Im rubbish at programming so I’d only really be testing the product/ hopefully showing it off! :stuck_out_tongue:

Basically I was wondering if its possible to make this wire frame function do 3 things.

  1. The tubes I have are just paper thin tubes. would it be possible to give them a thickness?
  2. Is it possible to have a ball socket where all the tubes join into (at the vertex)? or even more useful than that would be the ability to choose from a range of sockets eg.
    tapering the ends of the tubes into a ball socket

    having square sections and a web or set of gussets (i think its called)

The ball joint would probably be best (and maybe easiest to code?) and would be my preferred method
Any help at all would be very much appreciated!
