I have a weldment in which two of the bodies keep turning off whenever I bounce back and forth between the drawing and the weldment, so of course, they keep dissappearing in the views. If I go the model, turn the parts on, then go back to the drawing, and pick the view, click on "select bodies", it keeps turning them off, so I cant see them in the view. Is there some setting I'm missing or something? I've looked around in tools, RMB on the bodies and look in the properties, and don't see anything that could be causing this. Any suggestions?
