Behaviour of Creo Authored CAD Documents
Creo authored data are the CAD documents that are created in CATIA V5, NX, SolidWorks, Autodesk Inventor, Creo Elements/Direct Modeling and checked into Windchill through Creo. These documents are ‘Read-only’ in native CAD sessions that are connected to Windchill Workgroup Manager. You can perform Open and Save As actions on Creo-authored CAD Documents(models) in a CAD session connected to Windchill Workgroup Manager.
* 
A Warning message appears when you try to Open and Edit the Creo authored data in native CAD tool.
The same Warning message is displayed in the client message area as seen in the following image.
* 
An Error message appears when you try to export a Creo authored data which is checked-in to Windchill through Creo.
The Creo authored CAD documents are published by Creo CAD worker only and not by Native CAD worker.
Authoring Application Version Reference
The Authoring App Version Reference is used to distinguish between objects that are checked in by CATIA V5, NX, SolidWorks, Autodesk Inventor, Creo Elements/Direct Modeling and Creo authored documents. This Authoring App Version Reference is visible on the CAD document property page. The Workspace table display can be configured to show the value of Authoring App Version Reference. The following table shows the native CATIA V5, NX, SolidWorks, Creo Elements/Direct Modeling files checked in first time through Creo.
