Change the scale of the viewport I'm building a model that's very small, about a square millimeter, that I intend to have 3d printed. I've figured out the model at normal blender dimensions, with the units set to "None", and then I just set my units to "Metric" and scaled the thing down considerably.

Although I could use this model, I might want to make further changes, but since it's so small, it's difficult to work with since the viewport panning is messed up so closely zoomed.

How do I change the scale of my viewport from "meters" to something smaller, like "milimeters"? I've googled around and only find unrelated information.

Here's a screenshot to illustrate my problem.



Notice how in the top left corner of the viewport it says "User Persp" with "Meters" under it. I suspect that's what has to change.
You can change the scale of the whole scene to metric .001 (one thousandth of a meter=1mm).

Version 2.8X


Version 2.7X


But to be able to work at such small scale you also have to adjust the scale on the viewport as well:

For 2.8X The settings are in the overlay section.


For 2.7X they are in the Numeric Panel (N)


Here's what a 1mm x 1mm x 1mm object looks like in with such scaling:
