3ds max 2020 tutorials Scene Layout - Specifying display units And in the dialogue, we have the display units scale, and you can see that it is currently set to generic units, and that's the default. And we see over here we have a length of 46.549. Just to prove that generic units are actually inches, I'm going to switch the display units scale over to US standard and from the pull-down list choose decimal inches and when I click OK here, we should see this update. Click OK and now it says 46.549 inches. Alright, those are generic units. You will almost always want to explicitly set your units per scene. I'll go back into the Customize menu, to units setup, and I'll choose metric, with the pull-down list here set to centimeters, and click OK. And now it reads out in centimeters. The size of the object did not change. We're merely measuring it with a different system. And if I wished I can type in values here to make this a cube exactly one meter on a side. Type in 100, press tab, 100, tab, 100 and press enter. And now that box is one cubic meter. If for some reason you do need to use US standard units in feet and inches, then when you go into that customize units setup and choose US standard, you can choose feet or inches as your units. If you choose feet, either with fractional or decimal inches, then you also have the ability to choose a so-called default unit, and that's merely how 3ds Max will interpret your data entry.
