If you’re using Maya in conjunction with any other 3d systems, you’ve no-doubt been tripped up by having your working units set incorrectly. For years now I’ve been annoyed that the system seems to always default to centimeters while I’m generally working on projects that are measured in meters.
Today I’ve finally come to a solution easier than editing your UserPrefs script! If you check out the options for the File->New command, you’ll see that you can actually set the default unit to whichever you’d like. So unless you have an affinity for hours of leery-eyed aggravation, make sure you set your working units!
