I'm trying to add 16 bolt connections in my Solidworks Simulation but when I try I get an error stating bolt connections can only be created on circular holes. This is due to the hole starting on a circular tube, the hole is circular but on the surface it is an oval. Is there any work around for this? I would really like to use bolt connections as I need to find the forces acting on the bolts. The bolt connections are meant to secure the 3 truss sections to one another.

Thanks for your help!
