One of the promises with BIM, and tools like Revit, is that they will make your workflow faster and better with fancy features for calculations, coordination, and analysis.
It's easy to forget that it's also the tool we use to make the drawings, and we have to re-learn how to make good drawings when we switch to Revit.
It is common for the BIM Evangelists to get really excited about the fancy stuff (and justifiably so; this fancy stuff is actually really neat) and not put much effort into making the drawings look good.
Often, the BIM Evangelists have figured out how to make the drawings look good personally but then quickly moved on, figured it was trivial.
Then the rest of the production staff gets into the Revit environment and they are quickly over their heads trying to do the fancy stuff and make good looking drawings, at the urging of the BIM Evangelists.
The result is shitty drawings and broken fancy stuff. Two steps back.
BIM Evangelists tend to be really smart people who struggle to understand people who aren't as sharp as they are with software. This lack of empathy means they are likely to lead the group into deep waters before the rest of the pack is ready.
A successful BIM Implementation is all about timing. Walk before you run. Run before you fly.
Learn to fly before you jump off the cliff.
(A note: this applies to any firm where a significant number of people will have to work in the BIM authoring tool. If you only have one or a couple people who will be in the software, and they are all BIM savants, just stand back and keep them supplied with their caffeine delivery mechanism of choice.)
