Hello every one

I am trying to create a connection between a concrete deck defined as a shell and steel girders defined as wires, i have chosen to do this by creating an MPC connector type beam. i.e i created wire features and then assigned them with a beam type mpc in order to do this i used an orphan mesh.

see attached file for some pics

I keep getting these errors
