I do not (comprende) understand... how someone can have a CM title and does not know how to do powerful customizations - menus are pretty straight forward - like doing scripts.
But it must be just me.
I'm sure it's not just you, I suspect it's a cultural thing.
Here in the UK very few CAD managers I've met can customize, even less can automate with coding. As mentioned earlier in this thread, most CM's find themselves in this role because they'd been with the company the longest. Its also very surprising how few CM's have any formal training in their subject, even though we've had national qualifications for over 25 years now. The vast majority of British CM's will occupy the bulk of their time devising (& defending) their 150+ page standards detailing Layer names, linetypes, text sizes etc but will never give real time-saving measures a second thought.
(Obviously we all know that Layer "BX-01234-GHY-87-L" should be reserved for underground pipes dont we")
With the ever present need to lower staff costs, British companies are increasingly looking for very cheap over-seas draughting services (£3/hr) instead of investing in practical efficiency saving measures. Some simple automation in my current place of work has reduced draughting time for certain drawings from 3 days down to 30 minutes, multiplied by over 30 staff this amounts to some pretty impressive numbers.
I suppose the most efficient business model would be to combine cheap over-seas labour with a high degree of automation - I hope that moment arrives sometime after I've retired but I suspect it'll be happening a lot sooner than we expect.
