SANSCalc Online is a completely separate product from the Autodesk products. We have adopted a time based licensing system, currently available as 1-year licenses.
Updates will be released regularly and uploaded in the background, as any amendments are made to either the software or the SANS 204 standard. The Revit add-on will be revised each year to cater to the latest available release of Autodesk Revit, which will assist in transferring the parameters from Revit into SANSCalc Online automatically. This add-in is optional and not required for SANSCalc Online to work.
