The Import From Feature Classes/Tables command allows you to import to a schematic dataset any information related to a feature class or table stored in a geodatabase by creating a schematic feature class in relation with this feature class or table and associating it with a given diagram template.
The steps below detail how to use the Import From Feature Classes/Tables command. This function can be used from any schematic diagram template whatever the schematic builder on which it is based.
- Edit your schematic dataset using Schematic Dataset Editor.
- 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.
- Right-click the desired schematic diagram template entry in the Dataset Editor tree.
- Click Import From Feature Classes/Tables.
The Import From Feature Classes/Tables dialog box opens:  
- Browse to the geodatabase that contains the feature classes and/or tables you want to import.
- Select the desired feature class/table or feature classes/tables.
 
- Click Select.
The Select Feature Classes/Tables dialog box opens:  Each feature class/table item has a check box at its left, which is checked by default for all feature classes/tables that are going to be imported as schematic feature classes. An unchecked item with gray text (dimmed) is an item whose name corresponds to a schematic feature class that already exists in the schematic dataset. 
- For each of the items related to the feature classes/tables you want to import, do the following:
- Check its box in the Import column.
A dimmed item whose name corresponds to a schematic feature class that already exists can be checked; the command creates a schematic feature class associated with the same feature class/table with a number appended to its name. 
- Choose the type of schematic feature class you want to be created from the Import As drop-down list.
 
- Check its box in the Import column.
- Click OK.
The importing process starts. 
When importing is complete, the Dataset Editor tree shows the following:
- There is a newly created schematic feature class related to each feature class/table item that was checked in the list. The names of those schematic feature classes correspond to the feature class/table names from which they have been created.
- The geometry for the created schematic feature class is point by default for an object table, or it corresponds to the imported feature class' geometry.
- The created schematic feature classes are all associated with the schematic diagram template that was right-clicked before opening the Import From Feature Classes/Tables dialog box.
You must click Save  on the Dataset Editor toolbar for all the newly created items to be saved.
