Lately when I import customer stp / step files that contain a number of assemblies and parts a number of the assemblies have the warning triangle. If I save this step to a SW assembly format all these flagged assemblies are missing. And when reopening the saves SW assembly all those flagged assemblies /part are missing. What could be wrong? Checking include all referenced components doesn't help. Note that I can open these same step files in TurboCAD and all the parts/assemblies are there. Any ideas?

First check by opening those sub assemblies and sure they contains the component. Further when doing save, click on Save All and this can force SW to save them all.
