Hello,

I drawed a construction in the wrong unit (m instead of mm). How can I change that afterwards?

Many thanks for your help

Just tap the scale icon at the top corner. Then choose what units you want.

Hi,

Thanks for reply… unfortunately not working.  
It changes the unit but not the numbers. 1m is now 1000mm.  
I scaled it now down, but after this I need to correct the xyz position of the drawing.  
Any other way without down scaling and keep the xyz positions?

Change the units to meters.
