I implore you all. Do not waste your time, money and company resources on a program that can not even create a line for a simple site plan. For what most of us use to diagram a set of drawings, is it really worth more to do lighting calculations. this way, but it it does not even do point to point so that is not that great either.
This program is like buy a Ferrari with no tires and no engine. Looks fast and like it should be a great preformer, but ultimately it is just a car on blocks. It promises improvement in speed, but you still have to finish the fundamental processes in AutoCAD. It take me twice as long to do a simple 10,000 sqft building in Revit than it does to do it in AutoCAD, Excel, Visual and Word. Revit was supposed to eliminate all that.
Don't Waste your money, the program is not ready. I have no doubt that it will be some day. Architecturally it works great. But don't sucome to the pressure of an architect to use it for Electrical, Mechanical, and/or Plumbing. It is not ready and the Autodesk support is just not there to help either.
