AutoCAD Block Attributes Not Populating in block WTPart

We are using AutoCAD with Windchill Workgroup Manager and have configured attributes for AutoCAD blocks.

The attributes are correctly assigned and visible on the AutoCAD block. During check-in, the attribute values are getting populated/displayed on the main CAD document/part in Windchill, but the same attribute values are not being populated on the corresponding WTPart created from the AutoCAD block.

For example, our AutoCAD blocks contain attributes such as:

• BRED
• ALLW
• DEDAR
• DEDNO
• DESC
• DUNO
• DUQTY
• RWT

The values are available in the AutoCAD block, and the attributes are also visible on the main part in Windchill. However, the block-specific WTPart is not receiving the attribute values.

We have already configured the attribute mapping and are using the AutoCAD Blocks functionality to generate the WTPart structure.

Expected behavior:
The attribute values defined in each AutoCAD block should be propagated to the corresponding WTPart created for that block.

Actual behavior:
The attributes are populated on the main CAD document/part, but the values are not populated on the WTPart corresponding to the AutoCAD block.
