Creating schematic feature classes using the Import From Feature Layers command

As an ArcGIS Desktop user, you have probably already created a map, map template, or layers file with different feature layers for your GIS data. Now, if you want to use the ArcGIS Schematics extension to generate diagrams based on this GIS data, there is a simple and straightforward process to quickly start your schematic dataset configuration from this map, map template, or layers file using the Import From Feature Layers command.

The Import From Feature Layers command can be used to easily create schematic feature classes for all or part of the feature layers in this file and automatically associate them with a given diagram template; that is, the one you want to use to implement your schematic diagrams. During the process, there are also some other schematic parameters that are automatically configured:

The steps below detail how to use the Import From Feature Layers command to specify the content of the schematic diagrams based on a given schematic diagram template.

CautionCaution:

Before starting the following steps, make sure that the feature layers available from the map, map template, or layers file with which you want to work are correctly configured; that is, make sure that all parameters on the Source, Symbology, and Labels tabs on the Layer Properties dialog box are correct for all the feature layers from which Schematics will have to work.

Steps:
  1. Edit your schematic dataset using Schematic Dataset Editor.
  2. If the schematic dataset resources are not arranged in a tree view in the Schematic Items window, click Views on the Schematic Dataset Editor toolbar and click Project Tree.
  3. Right-click the desired schematic diagram template entry in the Dataset Editor tree.

    This schematic diagram template is the one you want to use to generate schematic diagrams based on the GIS features referenced in your map, map template, or layers file. Depending on the type of GIS data contained in this map, the builder specified for the schematic diagram template can be either of the following:

    • The Standard builder, particularly if your GIS features are organized into a geometric network
    • The Network Dataset builder when your GIS features are organized into a network dataset

    Note that using the Import From Feature Layers command starting from a schematic diagram template based on the XML builder may also be useful if all or part of the XML elements in input are associated with GIS features.

  4. Click Import From Feature Layers.

    The Import From Feature Layers dialog box opens:

    Import From Feature Layers dialog - initial content

  5. Click the ellipsis button (...) at the right of the Map or Layer File area.

    The Select a map or a layer file to import dialog box opens.

  6. Browse to the desired map, map template, or layers file that contains the feature layers you want to import and select it.
    CautionCaution:

    If you select a .pmf file, make sure it has been saved with extended settings. If it has not, Schematics will not be able to read it, and the Import From Feature Layers command will not execute correctly.

    The following screen shot shows the Select a map or a layer file to import dialog box content after having selected the MapToImport map document installed with the Schematics tutorials data.

    Select a map or a layer file to import dialog

  7. Click Add.

    The Select a map or a layer file to import dialog box closes.

    The Map or Layer File box in the Import From Feature Layers dialog box automatically fills with the path of the selected file as in the following example:

    All feature layers currently available from the table of contents of this file are listed in the Select the feature layers to import list.

    • Feature layers that compose geometric networks and that are available from the imported file's table of contents are listed under specific entries on the list whose names correspond to the geometry network names. These feature layers are offset to the right of the geometric network entry they are related to. For example, in the above screen shot, the ElectricNetwork_Net entry corresponding to the ElectricNetwork_Net geometric network groups all feature layers that comprise this geometric network and that are available from the ElecDemo.mxd table of contents.

      By default, if these feature layer entries are checked in the imported file's table of contents (that is, if they are displayed in the map), they are checked on this list; if they are unchecked in the file's table of contents, they are also unchecked on this list. Unchecking the geometric network entry on the list causes the unchecking of all the feature layer entries related to this geometric network.

    • The feature layers available from the imported file's table of contents that are not included in a geometric network appear on the list at the same level as a geometric network entry. In the above screen shot, the HartGIS.County entry corresponds to such a feature layer.

      By default, this type of feature layer entry is unchecked on this list even if it is checked in the imported file's table of contents.

  8. Check the feature layer entries you want to import in your schematic dataset; that is, check the feature layers for which you want the Import From Feature Layers command to create the corresponding schematic feature classes in the schematic dataset and associate with your diagram template.
  9. Check Import Layer Properties if you want the layer properties configured for the imported feature layers to also be imported.

    The layer properties imported from each checked feature layer will constitute the default schematic layer properties for the diagram template.

  10. Check Overwrite Layer Properties if you want existing feature layer properties in the schematic dataset to be overwritten.
  11. Check Add all geometric network feature classes not listed if you want all feature classes that participate in the geometric network to be automatically created during the process even if, in the TOC of the map specified in input, there is no feature layer for them.
  12. Click OK.

    The importing process starts.

When importing is complete, the Dataset Editor tree shows the following:

You must click Save Save button icon on the Dataset Editor toolbar for all the newly created items to be saved.

CautionCaution:

If you want to change the geometry or the type of any newly created schematic feature class—for example, if you want a point node schematic feature class to be changed to polygon node—you must make that change before saving. After saving, schematic feature class geometry and type are locked and cannot be changed.
