If your primary goal is to perform clash detection between, say, your structure and your mechanical systems, or if you want to ensure that your stair tower fits into the overall architectural design, then 3D can certainly be very handy for that. Now, don't get me wrong, 3D is very important and useful.
And you could be left with the impression that in order to be BIM, you must be 3D, and conversely if you have 3D, then you automatically have BIM. Often when you hear the word BIM, in the same sentence you'll hear people talk about 3D. But there is one common misconception that I want to address. Now, there's lots of different ways that you can achieve BIM, and Revit is an excellent tool to help us achieve it because it does many of the things that I've just described natively. Any of these things become possible when you have a rich and robust BIM. You might want to do lighting design or heating and cooling computations. Some examples of the benefits of BIM include performing design computations or energy analysis, or calculating structural loads. If all the parts and pieces that make up your BIM project are fully coordinated with one another and don't require any manual updates in order to keep them in sync, and if you have a robust and rich data source of information that can be used both internally by the system and exported out to the project team to do meaningful computations, then you have BIM. There is certainly more to it than that, but in my opinion, these are the two most important tenants of BIM. Revit is a tool used to help us achieve BIM, and BIM is a process that we follow to create building model data that is essentially two things: coordinated and computable. Revit is often described as being purpose built for building information modeling, and this is certainly true, but this often leads to confusion that somehow Revit and BIM are the same thing.
This term has been part of the AEC industry for many years now, and it's used to describe the process of creating virtual computer models that represent actual building facilities. But just what exactly is BIM? BIM stands for building information model or modeling. For starters, when folks talk about Revit, you'll also often hear them talk about BIM.
I know you're likely anxious to get into Revit and start working, but before we do, let's talk about a few high level concepts first.
