About Transferring the Meta Data of Chamfers from Creo Elements/Direct Preserving Design Intent
You can chamfer the edges between adjacent surfaces in Creo Elements/Direct Modeling. Based on the distance maintained between the edges, the following types of chamfers are created in Creo Elements/Direct:
• Constant distance chamfers—The distance between the edges along the adjacent surfaces is constant.
• Distance-distance chamfers—Two distances exist between the edges of the adjacent surfaces.
• Distance-angle chamfers—A specific distance and angle exist between the edges with respect to one of the adjacent faces.
When you open or import to Creo 3D models that are created in Creo Elements/Direct Modeling, the meta data that is attached to the geometry of the chamfer types present in the models are transferred to Creo. Although the chamfer types in the Creo Elements/Direct models are not imported as features to Creo, their geometry and design intent are preserved during the import. While it is important to maintain the design intent that was created in Creo Elements/Direct, the geometry of the chamfer types and their meta data that Creo Elements/Direct shares with Creo are useful in downstream Creo Flexible Modeling operations.
The meta data of the chamfer types that were created in Creo Elements/Direct Modeling are transferred to Creo without geometry changes and the meta data attempts to map to the corresponding parameters in Creo. When the meta data of a chamfer type does not find the corresponding mapping in Creo, the geometry of the chamfer type and its meta data are not preserved. Creo algorithm then recognizes the chamfer type as another type. For example, Creo algorithm recognizes the distance-angle chamfer type as the distance-distance chamfer type.
When the meta data of a chamfer type is not preserved after the import of the Creo Elements/Direct models, Creo algorithm does not recognize the chamfer type. You can then modify the geometry of the chamfer type in Creo Flexible Modeling or Creo Elements/Direct to maintain the design intent that was transferred from Creo Elements/Direct to Creo. When you use the Edit Chamfer command in Creo Flexible Modeling to modify the geometry of the chamfer and convert the chamfer type to a chamfer type that is recognized by Creo, the surfaces of the chamfer type highlights in red. When the geometry modifications are complete, the adjacent surface are highlighted in green color.
