Absolutely! I cannot imagine a CAD system that can't symbolically represent what is actually desired. The model and its spec should be one and the same. Approximations also open the door to different precision versions. Not helpful when different parts from different sources need to be consistent. Models that approximate/vary from the ideal spec, created intentionally to match manufacturing limitations, are ok.
