OS. Method Object Failed
Method 'OpenSTAADFunctionName' of object IOutput failed.
where OpenSTAADFunctionName is the name of an OpenSTAAD function. For example:
Method 'GetMemberBetaAngle' of object IOutput failed.
Check to be sure that you are passing all parameters required by the function. If a parameter is missing, or if the parameter being passed is not valid, the Method …of object IOutput failed message may appear. For example, the message may appear if a member number is passed to the function, but that member number does not exist in the currently open STAAD file.
