Multiple Joint on Beam


I`m trying to do a simulation on a hollow beam structure. When i enter simulation mode, i notice some of the beam joint having 2 purple joint dot ( as attached ). Can anybody explain to me why does this happen because the structure were created by using linear pattern of solid bodies, and majority of the joint were ok.

I suppose you work with 3dsketch and weldments. The purple spheres are joints. When you draw the sketch you must be precise .The final point of lines must be coincidents. A tiny difference generate two joints instead one
