When reading BIM files as ArcGIS features, ArcGIS Pro makes a correlation between elements in a BIM file and generates ArcGIS features with analogous geometric types. Certain objects in a BIM file may have multiple geometric interpretations. Floors, walls, windows, and doors may all be represented as 3D architectural features in a BIM model, which can be understood as 3D multipatch features in ArcGIS. Those same BIM elements can also be understood as the boundaries in a building floor plan and can be interpreted in ArcGIS Pro as a source of 2.5D floor plan geometry at an elevation.
Supported Revit geometry
Revit files (.rvt) contain objects that are classified according to a distinct list of object groupings called categories. These Revit categories are also used by ArcGIS Pro as the basis for feature class sources. These categories are generally in a construction discipline. The construction disciplines are used by ArcGIS Pro as dataset groupings for the resultant BIM file workspace. A BIM file workspace dataset called Floorplan is included for additional feature classes derived from the .rvt file content, which is useful for indoor mapping. The following is a list of the supported feature classes of the BIM file workspace, their dataset organization, example content, and geometric type:
