Error message:

where OpenSTAADFunctionName is the name of an OpenSTAAD function. For example:

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.

You may also receive similar messages if your version of STAAD.Pro is not compatible with OpenSTAAD.  OpenSTAAD is compatible with STAAD.Pro 2001 Build 1006.US.REL and higher. You will need to reanalyze your model in that build.  This is because we switched the way the data is recorded in Build 1006 to save more space.  Build 1006 US.REL was released in November 2001.

UK Builds prior to STAAD.Pro 2002 are not compatible with OpenSTAAD.
