Bradley, you are describing a situation that existed long before CAD ever came on the scene. My first job was on a drafting board while in high school. I was constatnly fed redlines to correct. It wasn't until about a year passed that I was given my first non-redline work to do (simple plot plans and electrical plans). But like you, I never blindly did redlines for the sake of doing them. I wanted to know why the redline was created, what inpact it would have, etc.
You touched upon the problem though, companies today think they can still have "drafting pools" with their CAD operators. Very few understand the fine line that exists between "pure drafting" and "design work" now involved when using any CAD program. CAD operators (not realy true drafters by my standards) today must understand the design they are modifying, what the best method of model modification is, and how their modifications will effect surrounding and associated models and design parameters.
These are hard things to learn from any book.
