When I go to Report Setup from within STAAD.Pro and try to select the output items, I do not see any of the items as shown in the picture below. How can I get these items back ?

Solution :

The Output items are not visible most likely because you have not analyzed the model or you may have modified the model which would erase any already existing analysis output data. To get back the Output items, simply reanalyze the model and the output items will reappear as shown next
