Doug Bowers has joined the blogger ranks and has some great tips to share for ACA along with Revit. Doug has taught at AU and is on some of the teaching vid's or articles I have downloaded over the years so you can be sure that he has and will have some worthwhile posts.
I have added his site to the links on the left.
Also Anthony Mason has just started a blog on "....CAD / BIM / Procedure / Support Application / AEC...". Anthony is a long time ADT/ACA user and now CAD manager (or is that now BIM manager?) and an active contributor on the newsgroups. He's just about to start a project in Revit Arch. so I am sure that will occupy his mind but hopefully he will still have some good tips to post for ACA.
