CAD itself is in it's infancy. The AIA put forth CAD standards but they are based on AutoCAD as it was then, and even the usage of AutoCAD has changed. The shortcoming of AutoCAD was the large number of layers needed to handle linework and the need to use color to designate line width. Other programs have moved beyond this and so has AutoCAD to some extent. So that layers can be minimized--objects can be filtered by type, or attributes and layers can reflect sheet setups or logical groups rather than having a layer for every type of line and data.

So trying to force everything into one CAD drawing standard can be a waste of time, as it will soon change in usefulness--and you create more work trying to comply. When I get drawings with many layers of unintelligible names--the drafter has usually left objects on the wrong layer already. It gets so complicated, people can't follow it.

Let the architectural office set the standard for the projects. The other consultants could then conform to it.

Perhaps the next generation of CAD will allow many people to work on drawings and comprehend the structure more easily--and stay in that structure, by the program interface ITSELF being more transparent and intuitive.

Imagine if it were a piece of vellum you were handing about across the planet. It would be more straight forward, but think of all the erasure burns and smudged pencil work!
