Is it possible to update CAD Document Attribute with java Code ?

Hello!

Maybe you can try the below code (in this case written for master attributes):

EPMDocumentMaster master = getMaster();

String attributeName = "MyAttribute";

String newValue = "MyNewAttributeValue";

LWCNormalizedObject lwcObject = new LWCNormalizedObject(master,null,Locale.US,new UpdateOperationIdentifier());

lwcObject.load(attributeName);

lwcObject.set(attributeName, newValue);

lwcObject.apply();

PersistenceHelper.manager.modify(master);

Best regards,

Peter
