mm in Part Studio - Inches in Drawing Studio

Hi,
When inserting the parts into a Drawing Studio, and when measuring, I get measures that are not in mm, in which I am working, and which correspond to the settings.
There are measurements that are neither mm nor inches, such as 0.386; this cannot be inches as they would be 9.8044 mm but the correct dimension in PartStudio is 12mm.
Other measurements are correct in inches: 36mm in the part studio, 1.417 in the drawing studio.
But why are the measurements in inches at all (for those that are correct)? And dow to change in mm for Drawing Studio too?
Kind regards
ProApe

The default template is an American standard and so is in inches…shakes head sadly… you want to select ISO which will be in mm.
If you're rolling your own template you can set to automatically fill in by double clicking on some note text and the dialog has the option to pick fields. (at least I think it's that easy, can't check right now as on phone).
It might also be worth checking that your workspace units are in mm. Three bar icon thing in the top right. You can set your default units by setting them in your profile.
It is quite simple. I'd better watch what I'm doing!
When I define the sheet as ANSI, inches are preset and I can select mm.
But that does not explain this strange measurement that is not in inches!
How can this be explained and which unit might it be?
……
But I have just noticed that the dimensions in the Drawing Studio are identical in mm and in inches after conversion.
But what is not correct: the correct dimensions of the parts are not taken from the Part Studio: 29.39mm in the drawing instead of 36mm in the Part Studio, 9.8mm instead of 12mm.
Dimensioning on the 2D drawing only works on orthogonal views (head-on). It does not work in isometric views (the tilted ones). That's why the numbers don't match up.
Ok, Thanks.
