Selecting Classes

The Classes tab of the AVEVA AIM Export Setup window enables you to select the classes to be exported. The classes you select here are included in the EIWM file.

Click the Add (+) icon to start adding the classes.

The following image shows the Class selection area in the simplified mode.

The following image shows the Class selection area in the Advanced mode.

To select classes:

1. Click the Add (+) icon to add a class.

   Note: If you want to remove a class, highlight the class in the grid and click the Remove (X) icon.

2. Do one of the following:

   • If you want to select the classes from the available grids:

     1. Select the From grid option. The grids available in the project are displayed in the Select grid to append classes from list.

     2. Select the required grid, and click Add. The classes available in the grid are added.

   • If you want to select the classes from the available database views:

     3. Select the From database view option. The database views available in the project are displayed in the Select database view to append classes from list.

     4. Select the required database view, and click Add. The classes available in the database view are added.

   • If you want to select the classes from the available drawings:

     5. Select the From drawing option. The drawings available in the project are displayed in the Select drawing to append classes from list.

     6. Select the required drawing, and click Add. The classes available in the drawing are added.

     Note: If you want to select the current drawing, click the Get current drawing name icon. The drawing you have selected in the Drawing Explorer or the drawing you have opened is selected in the list.

3. Repeat steps 1and 2 for adding more classes.

   Note: After the classes are added, the Active check box is selected by default. Clear the check box if you do not want the class to be exported. Further, the Filters column displays if a filter is applied on the class. For information on how to apply filters, see Applying Filters.

Class Selection Strategies

Due to the complex nature of AVEVA™ Engineering and the associated project data, it is advised to create the configurations so as to ensure that the publishing performance of the AVEVA™ Gateway for Unified Engineering remains optimal.

Models in AVEVA™ Engineering could often have large number of sub classes under a parent class. For such projects, publishing the graphical data of the topmost parent as a single model (single SVG file) can result in memory-related issues and sub optimal performance of the AVEVA™ Gateway for Unified Engineering. Therefore, it is advised to create configurations in such ways that generated SVG drawings would be split into multiple files of smaller sizes.

Dividing models into smaller parts for publishing is also beneficial in case of future model updates. Consider the case where a large SITE has been published as one model to AVEVA™ Asset Information Management and at a later point in time, it must be updated due to changes in source model. In such cases, the entire SITE need not be published once again if the graphical data has been split into multiple files.
