I have tried everything I can think of, so it is time to ask the experts. I have a large frame assembly that is not showing a sub-assembly in any of the views. Apparently no one has ever noticed this before; the print is at rev p now. I have checked the assembly, the model is there, not hidden, suppressed or blanked. In the drawing I have checked to see if the components have been blanked, and I get "no blanked models" response. I have also checked to see if the parts were put on a layer that got hidden, no help there. My last thought was that the lines were erased perhaps, so I made another view and still the sub-assembly does not show up. What am I missing?
