Composite wall build-ups - accurate material thickness

[Jen M]

Hello, 

See screenshot attached - is it possible to change the settings to reflect a more accurate measurement?

I'm trying to have the plasterboard 12.5mm thick rather than 13mm. It seems to always round up. 

Thank you.

If you input 12,5 - then it is set to 12,5. How it is displayed is controlled by the working unit settings under options > project preferences > working units.

It took me a long time to work this one out.  Of course, it is probably unlikely that plasterboard is actually manufactured to 0.5mm precision, but it is what it is sold as.
