Can I omit Basic dimensions?

My drawings are created (& read) in 3D format (MBD). I read an article that basic dimensions can be omitted in MBD; the main advantage being shorter dimensioning time. I only know 2 situations where basic dimensions are required:
(a) for designer's information (to track changes or apply in calculations etc),
(b) for CMM application

Does anyone know of other conditions which would utilize basic dimensions?
Does ASME have any rules regarding omission of basic dimensions?
Note that since I have provided the drawing in MBD, any unknown dimension can be checked from the 3D.
Hope to understand what I'm missing.

The 3DPDF is basically for reference. You would take your measurements from the MBD model.
