I work on CII mainly with EN Standrads and with metric system. I have a problem because CII does not accepts a value of WT equal 10 mm This value always is change to 6.375. How to solve this issue ??
You have to go to Configuration file, Database definition and to change Piping size specification from ANSI to DIN. This will solve your problem, but remember that the OD will not be updated automatically.
