Import CAD To Indoor Dataset (Indoors)

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

Summary

Imports features from CAD files to an indoor dataset 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

• Use this tool to load floor plan data into an Indoors workspace created using the Create Indoor Dataset tool or the Create Indoors Database tool.

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

• The Source CAD Data parameter value must be at least one .dwg or .dgn file.

  Caution:

  The tool imports one level (floor) of a facility at a time. If you have multiple CAD files with data for the same level, you can add multiple CAD files to the Source CAD Data parameter.

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

  Note:

  The target features must all be from the same file geodatabase, enterprise geodatabase, or feature service.

  • When features in the Target Unit Features parameter value are added, updated, or deleted, the tool creates a summary text file in the ArcGISProTemp directory. The summary text file lists any added, updated, or deleted unit features using the UNIT_ID and NAME fields.

• Provide the name of the level for the Level Name parameter. If the level exists in the target Levels layer, you can choose it from the drop-down list. If you choose an existing Levels layer, the Levels feature and associated Units and Details features will be updated. Field values from fields in the Levels and Units layers that are not populated by default will be preserved if they are not mapped using the CAD Annotation Mapping parameter. Details features will be deleted and overwritten.

• You can import features from CAD layers in the input CAD data, or add the CAD data to a map and import features from the polyline layers. Use the Select Layer From Source CAD parameter to specify whether to import from input CAD layers or from map polyline layers.

  • If the Select Layer From Source CAD parameter is checked, provide CAD layers for the Source CAD Layers for Units, Source CAD Layers for Levels, Source CAD Layers for Details, and Source CAD Layers for Facilities parameters. Optionally, include door entities in the Source CAD Layers for Doors parameter.
  • If the Select Layer From Source CAD parameter is unchecked, provide CAD polyline map layers for the Source Layers For Units, Source Layers For Levels, Source Layers For Details, and Source Layers For Facilities parameters. Optionally, include door entities in the Source Layers For Doors parameter. The tool honors selections and definition queries on input map layers.

• Provide the polyline layers that represent unit boundaries for the Source CAD Layers for Units or Source Layers for Units parameters. This can include a single layer that represents room boundaries, or multiple layers that, when combined, represent room boundaries (such as layers for exterior walls, interior walls, and doors).

• Provide the polyline layers that represent level boundaries for the Source CAD Layers for Levels or Source Layers for Levels parameters.

  If no value is provided for either parameter, the tool will create a level polygon feature based on the extent of the unit polygons.

• Set the Level Elevation parameter value as the elevation of the level in relation to the ground. The parameter value must include a numeric value and a unit of measure (international feet or meters). Z-values for levels, units, and details are populated based on this value.

• Provide an ordinal integer representing the vertical order of each floor for the Vertical Order parameter value. The vertical order of the ground floor is zero (0). Floors above the ground floor have positive vertical order values, and floors below the ground floor have negative values.

• Provide the polyline layers that represent facility boundaries for the Source CAD Layers for Facilites or Source Layers for Facilities parameters.

  If no value is provided for either parameter, the tool will create or update the facility polygon based on the extent of all the level polygons in the facility.

• Provide the polyline layers that represent features you want to import as polyline features in the details layer (such as walls, windows, doors, furniture, and so on) for the Source CAD Layers for Details or Source Layers for Details parameters.

• If the input CAD data contains door features that must be closed to create unit, level, or facility boundaries, use the following parameters to close doors:

  • For the Source CAD Layers For Doors or Source Layers For Doors parameters, provide the CAD or map layers that contain door features.
  • Optionally, set a value for the Door To Wall Distance parameter. The parameter value indicates the distance the tool searches from the door feature for the boundary of the related unit. The parameter value must include a numeric value and a unit of measure (international inches or millimeters). The default is 0.3 international inches.

• Use the CAD Annotation Mapping parameter to map CAD annotation to features in the Indoors model. At a minimum, it is recommended that you map information from CAD to the NAME and USE_TYPE fields in the Units layer. These field values are used to enable functionality in ArcGIS Pro and the Indoors web and mobile apps. The NAME field is also used in update scenarios when rerunning the tool to update features in the Indoors workspace.

  Set the values as follows:

  • Target Indoor Layer—Specify the layer in the Indoors workspace to which you want to map annotation. You can set Units, Levels, or Facilities as inputs to this value, which correspond to the parameter values provided for the Target Unit Features, Target Level Features, and Target Facility Features parameters. Mapping annotation to the Details layer is not supported.
  • Target Field—Provide the field from the target indoor layer to which you want to map CAD annotation.
  • Entity Type—Specify the entity type (Text or Block) of the CAD annotation you are mapping. If the CAD annotation is Text or MText in the source CAD data, choose Text. If the CAD annotation is stored as block annotation, choose Block.
  • Source CAD Layer—Provide the CAD layer that contains the CAD annotation you want to map.
  • Block Attribute—If you set the Entity Type value to Block, provide the name of the block attribute where the CAD annotation you want to map to the target field is stored. If you set the Entity Type value to Text, do not provide a value.
  • Delimeter—If the value you want to map to the target field is stored as delimited text, set the delimiter for this value. For example, if you have period-delimited CAD annotation such as CAMPUS.A.A-210 and you want to map the third part of the string (A-210) as the UNIT_NAME field value, use the period (.) as the Delimeter value.
  • Position—If the value you want to map to the target field is stored as delimited text, set the position of the value you want to map in which the beginning of the string is position 1. For example, if you have period-delimited CAD annotation such as CAMPUS.A.A-210 and you want to map the third part of the string (A-210) as the UNIT_NAME field value, use 3 as the Position value.

  Note:

  When targeting the Units feature class, if the CAD annotation is sourced from multiple CAD layers, you can provide multiple inputs to the CAD Annotation Mapping parameter targeting the same field. If more than one of the specified CAD layers contain annotations for a unit feature, the tool uses the CAD annotation from the first provided CAD layer that contains annotation for the feature.

• The Minimum Unit Width parameter indicates the smallest width a polygon must have to be considered a unit feature. The parameter value must include a numeric value and a unit of measure (international feet or meters). The default is 3 international feet.

• The Minimum Unit Area parameter indicates the smallest area a polygon must have to be considered a unit feature. The parameter value must include a numeric value and a unit of measure (square international feet or square meters). The default is 9 square international feet.

• Any polygons that do not meet the thresholds set by the Minimum Unit Width or Minimum Unit Area parameters are copied to a scratch feature class in the default geodatabase of the ArcGIS Pro project. You can inspect the scratch feature class polygons and append any of them to the Units layer as needed.

• If a level feature exists with the same name as the Level Name parameter value, the level and its associated units and details features will be updated as follows:

  • The levels feature will be updated. Any attributes that are not populated by default, including custom fields, will be preserved.
  • The tool will compare unit features between the CAD drawing and the Units layer. If units with matching names or geometry are found, they will be updated. Any fields the tool does not populate by default that are not mapped using the CAD Annotation Mapping parameter will be preserved. Features that are present in the CAD drawing but not in the Units layer will be added. Features that are not present in the CAD drawing but are present in the Units layer will be deleted.
  • Details features will be deleted and reimported from the CAD drawing.
  • If map layers are provided as the inputs for units, the tool will honor any definition queries or selections applied to those layers.

  Note:

  If the Level Name parameter value does not match the NAME field value for an existing level feature, the tool imports the CAD drawing as a new level with the specified Level Name value.
