The following pictures include what weldments are giving me and issue. I have 2 bars that are coped to a small (tab) bar. I used the combine feature to make them a single structural member, but still have issues when trying to use FEA. I'm very new to weldments so i'm sure it may be something simple that i'm missing to make these peices stay bonded. When I go to run solidworks simulation on the frame, the weldments disappear after meshing.. Any helpful info is greatly appreciated.
