Adding an entity type

To add an entity type to a relationships diagram, do the following:

  1. On the Diagram tab of the Relationships Diagram, click Entity Type.

    The Add New Entity Type From Layer dialog box appears.

  2. Choose a layer or a standalone table from the Select Layer drop-down menu.

    Only data sources with a field of the "Object ID" data type are listed in the drop-down menu.

  3. Select a field from the Select a field for entities drop-down list.

    This field should represent the entities that will be represented as individual nodes on the diagram. This field can be any valid field of the type "String", "Date", "Double", "GUID", "GlobalID", "Integer", "OID", "Single", "SmallInteger" or "XML".

  4. Enter a name for the entity type in the Enter a name for entity type text box.

    This helps to distinguish between entity types that come from the same dataset.

  5. Optionally, select the Hide duplicate entities check box.

    In this case, all duplicate values ​​in the field specified under Select field for entities are displayed as a single node.

  6. Click OK to load the entities into the relationships graph.

    Individual entity types are loaded into the relationship diagram and displayed as nodes. The symbolization of the nodes corresponds to the symbolization of the source layer. If the source of the entities is a standalone table, the symbolization of the nodes is set to a single symbol by default. To change the symbology, select the entity type in the Contents pane and click Symbology on the Diagram tab of the relationships graph, or right-click the entity type and click Symbology.


    Changes made to the data sources; For example, newly added records, updated record attributes, or deleted records are not automatically synchronized with the relationships graph; To do this, you must first click Refresh in the relationship diagram view area. The time the relationships graph was last synchronized is shown in the Status label in the relationships graph view area.

  7. Optionally, click Entity Type and repeat the steps above to add more entity types.

    You can add as many entity types as you want, as long as they all come from data on the same card. For example, there may be a relationships diagram with entity types from multiple layers and entity types from the same layer that have different fields to define the entity field.

  8. Optionally, edit the parameters of an existing entity type.
    1. In the Contents pane, right-click the entity type and click Properties.

      The Entity Properties dialog box opens.

    2. Make your changes and click OK.

      The diagram is updated.

Change the node symbology

Layer-based nodal sets use the same symbology as the layer by default, while standalone table-based nodal sets use single symbols by default. To change the symbology of a node set, do the following:


In small-scale relationship diagrams, nodes are represented by a simple icon in a standard color. If you want to adjust the default color, select the Override icon color of overview node option and choose a different color from the color picker.

  3. To return to using map symbology, select Map symbology.
  4. Click Icon to activate the icon gallery and select an icon for the nodes.

  6. Click the symbol again, then click the Properties tab and edit the symbol properties.
  7. Optionally, edit the label properties.
    1. In the Contents pane, right-click the entity type and click Properties.
