Revit is an Autodesk product that creates geometry that is more complex than standard AutoCAD geometries. For example, the geometry that is created is not a simple line like AutoCAD, but geometry that contain complex data for objects such as walls and doors, allowing engineers to classify the objects with real-life information.
The Revit model is essentially all the parts of a structure assembled virtually in 3D and contains all the information to identify what and how these parts are built. Organizations involved in the engineering, architecture, surveying, and construction industries use these to create Revit files that follow building information modeling.
Building information modeling
Building information modeling (BIM) is often a 3D computer-aided digital design for a real-world structure. Building information models are used to simulate a physical object to ensure it can be created with its current parameter implementations. Building information model parts of the geometries also contain the physical and logical characteristics of the built environment. The geometry will show a chair, but the attributes will contain the model, size, ID number, and so on. The more details put into BIM, the more information that can be pulled out of the model to bring value to the project.
Although it is possible to create CAD data that corresponds to the x,y coordinates of a projected grid zone, most CAD data is authored without this consideration. Typically, features are measured relative to other features using distances that have been measured at local ground elevations.
Revit and BIM
Revit supports BIM. Revit helps designers design, simulate, visualize, and collaborate to effectively create data that is interconnected. The data follows the BIM standard so that it can be correctly interpreted by any organization or product, ensuring all geometries and attributes can be organized as expected. This allows a product such as ArcGIS Pro to use not only the 3D geometries, but also the properties from the drawings.
ArcGIS Pro ArcGIS Pro 2.3 supports Autodesk Revit 2015 through 2019 file formats (*.RVT). When earlier Revit files are accessed through ArcGIS Pro, they are temporarily upgraded to the latest Revit file format. For best performance, permanently upgrade your Revit files to the latest supported version.
