I am a student looking for some help modelling a roll cage. I have completed the roll cage, but I cannot create welds between the joints. The cage has been made in a single part, with a few planes for reference. I have tried using the Weldment feature but, when selecting Weld Bead, I cannot select anything for the second face. This seems to be tricky because I am welding round pipes into each other. I don't really want to create the pipes individually and mate them, because this seems like it would be a huge pain in the ass.
Any help would be appreciated.
Thanks for your time.
