Have updated to STAAd Offshore Version 220.127.116.11 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.
Open the OpenSTAAD configuration file in TextPad or NotePad:-
C:\Program Files\Common Files\BentleyShared\IEG\OpenSTAADBentley\Data\STAADlib.cfg
Change the BaseUnits…
