A schematic diagram in ArcMap displays in a schematic layer. Whether this schematic layer already displays with default layer properties or not, you can redefine all the feature layers properties, change the feature layers order, and set reference scale at any time for this schematic layer. Then, if you want the newly specified layer properties to be set as default for the schematic diagram template, you can export the schematic layer as a layer file before importing it at the diagram template level using the Schematic Dataset Editor. The following steps explain how to set default schematic layer properties for a schematic diagram template when starting from a schematic layer in ArcMap.
- Start ArcMap.
- Click Windows then click Catalog.
The Catalog window displays.
- Navigate in the Catalog tree to the schematic dataset that contains the schematic diagram template for which you want to configure the default symbology.
- Add a schematic layer related to that diagram template in the map by doing one of the following:
- Drag any schematic diagram entry based on that template on the Catalog window and drop it on the map.
- Right-click the schematic dataset entry in the Catalog window and click Show/Hide Schematic Classes. Then drag the entry corresponding to that schematic diagram template and drop it on the map.
- Start setting the feature layers order by right-clicking the schematic layer in the table of contents and clicking Properties.
- Click the Layers tab in the Layer Properties dialog box that opens.
- Select the layer entry for which you want to change the drawing order in the Layers list and click the up or down arrow buttons that display at the right to move it up or down. You can also drag and drop the entry to the desired location.
- Click Apply and click OK.
- Then if you want to modify properties set on any feature layer that composes the schematic layer, right-click this feature layer entry in the table of contents and click Properties.
- Click the appropriate tab in the Layer Properties dialog box that opens and make the changes you want to get the expected symbology, labels, selection style, and so on.
- Click Apply and click OK.
- Repeat step 4 for any feature layer you want.
- Then to set the current scale of the data in the schematic layer as the reference scale to which all symbol and text sizes used in the schematic diagram will be made relative
- Right-click the schematic layer and click Reference Scale > Set Diagram Reference Scale.
- Click the Zoom In tool or Zoom Out tool to verify that the current reference scale corresponds to your needs.
- When all properties currently specified for this schematic layer correspond to those you want to be set as default layer properties, right-click the schematic layer entry in the table of contents and click the Save As Layers File menu.
- Save the resulting layer file somewhere on your disk.
- Right-click the schematic dataset entry in the Catalog window and click Edit . The Schematic Dataset Editor opens.
- Right-click the schematic diagram template entry in the Dataset Editor tree and click Import Default Symbology.
- Browse to and select the layer file you created at step 10.
- Save your schematic dataset.
Any schematic diagram based on this diagram template will now display with these new imported schematic layer properties by default.
