Have updated to STAAd Offshore Version 3.0.0.9 and the Base Units are set to Imperial. On the old version i just changed the base units to Metric as seen below, but in this version the file "STAADlib.cfg" doesnt seem to exist.
Version 2.0.6.1
Open the OpenSTAAD configuration file in TextPad or NotePad:-
C:\Program Files\Common Files\BentleyShared\IEG\OpenSTAADBentley\Data\STAADlib.cfg
Change the BaseUnits command to:
[BaseUnits]
BaseUnit=Metric
