Tag Classes in Graphical Data

When you are exporting graphical data, you can specify how the tag ID of the class must appear in the XGL/ZGL/RVM file through the Graphics tab in the Class Mappings page. The tag ID for the class is retrieved from the mapping specified here and the same is displayed on the XGL/ZGL/RVM file when the class is selected.

Note: Tagging is supported only for those classes that can be selected in the XGL/ZGL/RVM file. Accordingly, the settings in the Graphics tab are applicable to only those element types.

To map the tag ID and model name of a class:

1. Click the Models tab, and then click Class Mappings.

2. Select the required class in the class list.

3. Click the Graphics tab. The Tag ID, Model name and Folder name areas appear.

   

4. For the Tag ID area, do one of the following:

   • If you want to specify the mapping value for the tag ID directly, select the Constant option and enter a value in the Text box. The specified value is used as the tag ID of the class.

     Note: You can add the value to the list by clicking the Add icon. Click the Delete icon to delete the selected value from the list. When you delete a value from the list, the mapping for the tag ID is also deleted.

   • If you want to derive the tag ID from the value of an attribute, select the From Attribute option and select an attribute from the Attribute name list. The attribute value is used as the tag ID for the class.

   • If you want to derive the tag ID from a PML expression, select the From PML option and enter a PML expression in the PML Expression box. The result of the PML expression is used as the tag ID for the class.

     Note: When the graphical output is set to RVM, the Tag ID is same as the element name, for example /D1201 or /SITE-PIPING-AREA01. As a result, the Tag ID area is not available when the graphical output is set to RVM. The tag IDs for the classes without a mapping are not displayed in the XGL/ZGL/RVM file.

5. For the Model name area, do one of the following:

   • If you want to specify the mapping value for the model name directly, select the Constant option and enter a value in the Text box. The specified value is used as the model name of the class.

     Note: You can add the value to the list by clicking the Add icon. Click the Delete icon to delete the selected value from the list. When you delete a value from the list, the mapping for the tag ID is also deleted.

   • If you want to derive the model name from the value of an attribute, select the From Attribute option and select an attribute from the Attribute name list. The attribute value is used as the model name for the class.

   • If you want to derive the model name from a PML expression, select the From PML option and enter a PML expression in the PML Expression box. The result of the PML expression is used as the model name for the class.

6. (Optional) For the Folder name area, do the following:

   • If you want to specify the mapping value for the folder name directly, select the Constant option and enter a value in the Text box. The specified value is added to the EIWM Object Mapping area.

   • If you want to derive the mapping value from the value of an attribute, select the From Attribute option and select an attribute from the Attribute name list. The attribute is added to the EIWM Object Mapping area.

   • If you want to derive the mapping value from a PML expression, select the From PML option and enter a PML expression in the PML Expression box. The PML expression is added to the EIWM Object Mapping area.

     Note: Invalid file name characters (* ? " < > |) are replaced with an underscore ("_").
