Import BIM To Indoor Dataset (Indoors)

Available with the ArcGIS Indoors Pro or ArcGIS Indoors Maps extension.

Summary

Imports features from a Revit file (.rvt) to an Indoors workspace that conforms to the ArcGIS Indoors Information Model. The output of this tool can be used to create floor-aware maps and scenes, as well as to generate an indoor network for routing.

Usage

• You can use this tool to load floor plan data into an indoor dataset created using the Create Indoor Dataset tool or an Indoors geodatabase created using the Create Indoors Database tool.

• The source BIM data must be georeferenced before running the tool.

  Caution:

  Ensure that the BIM data is accurately georeferenced (including any linked Revit models) and the coordinate system of the indoor dataset and indoor 3D dataset match the coordinate system in the associated .wld3 file. Both the horizontal and vertical coordinate system units must match, and any linked Revit models must have the same horizontal and vertical coordinate systems as the host Revit model. Inaccurate georeferencing or mismatched coordinate systems can result in scaling issues for 3D features.

• The Input BIM Floorplan Polygon Layer parameter value will be the Floorplan_Polygon feature layer from the Floorplan dataset in the source BIM file workspace.

  • The tool uses the Floorplan_Polygon layer to construct the Levels and Units features.
  • Based on the Input BIM Floorplan Polygon Layer parameter value, the tool accesses additional layers from the same Floorplan dataset to construct the indoor dataset. The Footprint layer is used to construct the Facilities features, and the Floorplan_Polyline layer is used to construct the Details features.
  • You can select linked Revit files as input to the Linked Files parameter, which will appear automatically if the input Floorplan_Polygon layer is sourced from a host Revit model with linked files.

  • Linked Revit files must be located in the same folder or nested folders in the same folder as the host Revit model to be detected by the tool. You must input the Floorplan_Polygon layer of the host Revit model for any associated linked Revit files to be detected.

    Note:

    The tool only supports importing linked models that are .rvt files.

• The Design Options parameter is enabled when Autodesk Revit design options are detected in the Revit drawing. Design options exist alongside the main Revit model and are typically used during the design phase of construction projects. Design options are organized into sets, and only one option in each set can be assigned as primary.

  Design options for any selected linked Revit files will automatically appear for selection under the Design Options parameter.

  The tool always imports features from the host model of the Revit drawing. If needed, visualize the Revit drawing in a scene to determine which design options should also be imported. For example, use a definition query to filter the BIM floor plan polygon layer by floor; then symbolize the layer using unique values in the Option_Set and Design_Option fields.

  Note:

  After running the tool, inspect the imported Units and Details features. Depending on how the design options were organized, you may find extra or missing features. Running validation rules can help identify issues related to design options, such as overlapping features.

• The Target Unit Features, Target Detail Features, Target Facility Features, Target Level Features, Target Unit 3D Features, Target Detail 3D Features, and Target Facility 3D Features parameters must reference feature classes or feature layers that conform to the Indoors model.

  Note:

  Target 2D features must all be from the same file geodatabase, enterprise geodatabase, or feature service.

  Target 3D features can be from a different workspace than target 2D features.

• The Facility ID parameter is used to populate the FACILITY_ID field for the imported facility features in the indoor dataset. Keep the following in mind when setting this parameter:

  • Spaces are not allowed. You can replace spaces with underscore characters. For example, instead of Building XYZ, use Building_XYZ.
  • To add the input BIM data as a new facility in an existing indoor dataset, specify a facility ID that is not assigned to another facility in the target facility features.
  • To update an existing facility, use the FACILITY_ID field value for that facility feature in the target facility features.

    Note:

    To update an existing facility feature, the Facility ID parameter value must match the facility feature's FACILITY_ID field value, and the Facility Name parameter value must match the facility feature's NAME field value. The matching is case sensitive.

• The Facility Name parameter is used to populate the NAME field for the imported facility features in the indoor dataset.

• The Ground Floor Name parameter defines the ground floor of the building. The vertical order, level number, and z-value for each level in the target level features are derived from this input. Any levels with an elevation that is less than the defined ground floor are assigned a negative vertical order.

  Note:

  • You do not need to import the floor you set as the ground floor to the indoor dataset.
  • Only occupiable levels are accepted as inputs for this parameter.

• If data exists in the locations you set for the target feature parameters, the Facility and Level names in the source BIM file will be compared to the Facility and Level names of the features to determine the features to update.

  • A Facilities feature will be updated if the Facility ID and Facility Name parameter values match the FACILITY_ID and NAME field values, respectively, for a target Facilities feature.
  • A Levels feature and its associated Details and Units features will be updated if the BldgLevel field value for a Levels feature in the source BIM file matches the NAME field value for a target Levels feature.

  Note:

  If the Facility ID and Facility Name parameter values do not match the FACILITY_ID and NAME fields for an existing facility feature, and the BIM floor plan polygon does not intersect an existing facility feature, the tool imports the BIM data as a new facility with the specified Facility ID and Facility Name values.

• The Floorplan Polygon Use Type Field parameter defines the field from the Floorplan_Polygon feature layer that will be used to populate the USE_TYPE field for the target Units features. If no field is provided, the RoomName field value from the Floorplan_Polygon layer will be used.

• You can map additional attributes from the Rooms layer in the source BIM file to existing fields for the target Units features using the following parameters:

  • The input BIM Rooms Layer parameter defines the Rooms layer located in the Architectural dataset in the source BIM file.
  • The Room Properties Mapping parameter can be used to map fields from the input BIM Rooms layer to target unit feature fields. Fields must exist before you run the tool. It is recommended that you map fields from the source BIM Rooms layer to target fields that have the same data type.
  • If you selected linked files for import using the Linked Files parameter, you can map to fields in the Units layer from multiple Rooms layers. The selected Rooms layers must be sourced from either the host Revit model or any selected linked Revit files. If a field is mapped from one Rooms layer and that field exists in multiple linked files, the field will be mapped to any units created from the linked files during the tool run.
  • You can't use multiple input layers with the same name in the Room Properties Mapping parameter. Instead, use the Browse button in the Geoprocessing pane to browse to the full path locations of each of the Rooms layers.

• The following fields are mapped by default if they are in the Units feature class and cannot be mapped using the Room Properties Mapping parameter: AREA_GROSS, AREA_NET, AREA_UM, ELEVATION_ABSOLUTE, ELEVATION_RELATIVE, FACILITY_ID, FACILITY_NAME, LEVEL_ID, LEVEL_NAME, LEVEL_NUMBER, NAME, UNIT_ID, USE_TYPE, and VERTICAL_ORDER.

• You can use the Floors To Import parameter to define the floors in the input BIM file that will be imported in the following ways:

  • Add or update specific levels in the indoor data.
  • Import levels with associated floor or roof elements.

  If an input is provided to this parameter, only that subset of data will be imported. If no input is provided to this parameter, all floors from the BIM file will be imported. Roof elements will only be imported if provided as input to this parameter.

• Use the Area Unit of Measure parameter to specify the units for the AREA_GROSS field in the Levels and Units feature classes.

• Use the Allow insert of new overlapping facility parameter to prevent accidental import of conflicting floor plan data.

  • This parameter is unchecked by default. When this parameter is unchecked, the tool tests whether the input BIM floor plan polygon intersects any existing facility polygon in the target facility features. If an intersection is detected, the tool checks whether the specified Facility ID and Facility Name parameter values match the FACILITY_ID and NAME field values of the intersecting Facilities feature. If the values match, the tool updates the existing facility. If the values do not match, the tool issues a warning message and stops running.
  • When this parameter is checked, the tool does not test whether the input BIM floor plan polygon intersects any existing facility polygon in the target facility features. Check this parameter to import a building that overlaps or touches an existing facility.

• Use the Target Facility 3D Features, Target Unit 3D Features, and Target Detail 3D Features parameters to import features into the Facilities 3D, Units 3D, and Details 3D multipatch layers. Features will be imported to the target layers as follows:

  • Target Facility 3D Features—Multipatch features will be created in the Facilities 3D layer representing the facility shell of the building from the ExteriorShell feature class.
  • Target Unit 3D Features—Multipatch features will be created in the Units 3D layer representing the footprint of objects in the Revit model's Rooms category.

  • Target Detail 3D Features—Multipatch features will be created in the Details 3D layer from objects in the following Revit categories: Doors, Ramps, Stairs, Stair supports, Stair Landings, Columns, Structural Columns, Walls, Windows, Cornices, and Curtain Wall Panels.

  • Symbology is generated based on the symbology of the Revit model.
