Using Revit is the equivalent of putting a loaded gun to your head and pulling the trigger.
The problem is that the gun is not a revolver with only one bullet, but instead a semi-automatic pistol that already has a round in the chamber, guaranteeing that you will not only blow your own head off (and probably manage to clip someones arm or leg with the ricochet), but the survivors will be responsible for cleaning up the fucking mess that you left behind.
I get handed a project, told 'this has to be done in Revit', but the fee is microscopic. 'Oh - these will be prototypes - so we'll make our money back later' is the Revitards response. The problem is that not only are they NOT prototypes (each one going into a differently shaped building) there's really no such thing as a 'Revit Prototype'.
You will be doing this shit, from scratch, every single fucking time. With equally retarded schedules, none of the information you repeatedly request, and no money to take a trip out to the site to see if the shitty fucking building they are trying to cram it into even has capacity for it.
People are amazing with how willing they are to assume that things will 'just work', despite repeatedly running into major problems that could have been avoided by asking some fairly basic questions at the beginning of a project - of course, since they were busy setting up the project in Revit, and making assumption after assumption in order to pound a passable (albeit still extremely shitty looking) set of drawings, they couldn't be bothered with 'details'.
