Hi,
I have a model which I created in STAAD SS4. I then had my machine updated to SS5 due to a licencing problem with SS4. I was led to believe that SS4 and SS5 were fully compatible with one another.
I don't believe this is the case, and wanted to ask if my problem is a known error in the software or if I am missing something obvious!
With the original model in SS4 I had extracted corner stresses from several locations. I took these and used them in my design calculations as normal. Later, after my copy of STAAD was updated to SS5, I had to go back into the model to make a modification. As I had done before, I extracted the corner stresses. However, this time the lower flange (of a standard UB section) did not report the corner stresses at the correct locations. I cannot understand why.

This error appears to affect all models created in SS4 and then re-analysed in SS5.
I only noticed this error after manually swithching on the labels in the graphical display. Had I not done this I would have made a serious error as the software gave every indication that it was providing the 'corner' stresses.
Is this a known issue?
