As the building information modeling process has become more sophisticated, the resulting models have grown larger. Think of that line from the movie Airplane!:
...and Leon's getting larger.
To allow computer applications to address larger models, applications like Revit have moved to 64-bit. In programming terms a 32-bit pointer can only directly address 4 gigabytes of memory whereas a 64-bit pointer can address 17.2 billion gigabytes. The extra available memory space allows building information models larger than 4 gigabytes to be loaded without the need to use some form of indirection. In other words, the application doesn't have to break the model into several 4 gigabyte chunks and also keep track of what's in what chunk. It can just reference parts of the building information model directly. The result is better performance for large information models on 64-bit applications.
Today we updated the STL Exporter for Revit Platform to support 64-bit versions of the Revit family.
Now if you have a large building information model, you can print it in 3D and touch the result. So give it a try and share your results: [email protected]. We love it when you send pictures of your printed building information models.
