By default, each block only represents one object type in the vault and that type has a specific naming standard. If your blocks can represent multiple object types (each with a different naming standard) and the object type is specified in a document property, you can specify which naming standard should be used depending on the value of the document property.

To configure alternate tag names:

1. In the TagExtraction section described in Configuring drawing tag extraction, create settings using the descriptions in the following table.

CaseProperty=<PropertySetName.PropertyName>

CaseProperty=Custom.UnitType

CaseValues=Chemical,Electrical,Mechanical

2. In the TAGBLOCK section described in Configuring drawing tag extraction for each block that represent multiple object types, add a setting for each value listed in CaseValues and specify the corresponding naming standard. The naming standard can be specified similar to that described in Combining multiple attribute tags. Any property values not listed here or documents for which the property specified for CaseProperty is empty will receive the default object name.

Following is an example of one complete TAGBLOCK section configured for alternate object names:

[TAGBLOCK_BLOCK1]
TagProperty=TAG_NO
TagType=Equipment
Chemical=[PROCESS]-[FLUID]-[NUMBER]
Electrical=[NUMBER]

In this example for a block named BLOCK1, all object names are linked to the object type Equipment (the default for the block). Objects related to documents for which the UnitType property contains Chemical are named with the PROCESS, FLUID, and NUMBER attribute tags. Objects related to documents for which the UnitType property contains Electrical are named with only the NUMBER attribute tag. Objects related to documents for which the UnitType property contains any other value are named with the TAG_NO attribute tag.
