I am going to play "devil's advocate", and ask, what do you want the CAD manager to do.
In a well established CAD/design group, where everyone is expereienced, senior and good, training may not be a top priority where most people are doing it on their own initiative already. In a young/inexperienced group, training may be more important.
Is the intent to trim cost? If so, a CAD manager will need to have more financial/managerial expertise. Knowledge of the current CAD software revision (and I like to highlight "currently") is less important. The last time I CADed, the version I belive was AutoCad 9.
A trait is only important if it is needed. If you evaluate what it is you need your CAD manager to do, the important traits should fall out of your evaluation.
