Units from millimeters to inches

[David_L_Aery]

i always use small inches when i open or create a file.

i have opened some files in mm to see if they will export in the correct scale.
now I have opened a file that was saved in inches and somehow is in mm, wrong scale when i import a file.

where can i change it back to inches?
Thanks

It’s under “Units” in the Document Properties. But I always just right-click on the unit in the bottom bar of Rhino.

When changing the unit it will ask if you want to scale everything and I can never remember which option is the correct one

Hi David -

I’m not sure what that means. You can’t “open” a file using different units than what it was created with or set to.

[…] wrong scale when i import a file.

Wrong scale or wrong units? Are you exporting to the 3dm file format or some other format?
