Good Day Everyone,
I have completed a staad model of a g+3 residential building, however I have been recieving the following warning in assigning the fc and fy values from IS456code. WARNING- "DESIGN CODE LISENCE WAS NOT ACTIVATED". and also an error which was commonly occurring in others app also was," ** ERROR : NO SURFACE INCIDENCE HAS BEEN PROVIDED YET." Does any one know why this would occur? I have added the Staad file as a reference as well.
