Map Object ID

You can modify the default mapping or specify another mapping for the object ID.

To define the object ID mapping:

1. On the Drawings tab, click Class Mappings.

2. Select the required class from the class list. The default mappings for the class, if any, are displayed in the EIWM Object Mapping area on the EIWM tab.

3. If the class has a File root, and if you want to add the object to the file, select File and right-click and select Add Object. Else, right-click anywhere on the empty space in the EIWM Object Mapping area, and select Add Object. The Object ID with or without a default mapping is displayed.

4. Select the root of the object tree Object. The Object ID area appears.

   

   Do one of the following:

   • If you want to specify the mapping value for the Object ID 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: The objects without a mapping are displayed in red.

Resolving Duplicate Objects

At the time of creating the configuration, you can specify what needs to be done if two or more objects have the same Object ID. The Advanced Options area enables you to specify how to handle duplicate objects:

The following options are available:

• Keep: If you choose this option, the original object is retained in the EIWM file and all other objects are ignored. All the values of attributes correspond to the values in the original object.

• Append: If you choose this option, the original object is retained in the EIWM file but any missing attributes are appended from the remaining objects. The values of the attributes correspond to the values in the original object first, but if the attribute is not present in the original object, the value corresponds to the attribute in the new object.

• Replace: If you choose this option, the original object is replaced with the new object. All the values of the attributes correspond to the values in the new object.
