Have a look at the screenshot I've uploaded . . . You'll see that the only way to change their color is by changing the color of the fully defined sketch lines. It seems to be impossible to have a fully defined sketch with dimensions being a different color than the fully defined lines. Am I the only one who finds that annoying?
Excuse me, while I give this a little bump.
Maybe it's a stupid question, but has anyone out there found a way to change just dimension colors, in a fully defined sketch while in sketch-edit mode?
