Mr Biswa is it possible to change the Units from Meters to Millimeters after creation of the total model
if so can u plz guide me for doing the same
Open the STAAD Input file by going to Edit -> Edit Input Command File. After the line END JOB INFORMATION change line UNIT METER KN to UNIT MMS KN.
Also, add line UNIT METER KN before the line DEFINE MATERIAL START in the input file.
