I haven't gotten a chance to even DL the trial yet, but I'm going to. Its based on Microstation, i suppose, since you must have the latter to try out the former. Ive never used either, but in the spirit of staying Objective about Revit I'm going to Download it this weekend.
Granted, i haven't spent a great deal of time with the various platforms I've used... But I've used a few, and i prefer it that way. So far I've been the happiest and most successful with Revit, for a number of reasons. Yet, having been down other roads always offers perspective, and from it, appreciation for the things we have. :)
Anyone try Bentley Architecture yet?
