About Modifying non-Creo Part Models Containing Bodies
You can modify the non-Creo part models or the part components of assemblies in Creo and apply the design changes to the models. However, when you try to merge, intersect, subtract, or split a body using commands on the mini toolbar or click Boolean Operations orSplit Body on the Body tab of Creo, the Confirmation dialog box opens. It states that the design changes you are about to make will not propagate to the native models. It prompts you to use the Save a Copy command to convert the non-Creo part models to Creo models before you proceed with the changes.
Additionally, while redefining the import features of non-Creo models, if you click on the Import tab and access Import DataDoctor (IDD) to repair the geometry of the import feature in IDD, you are warned that repairs and other changes made to the geometry of non-Creo models are lost when you perform an update using Associative Topology Bus (ATB). IDD warns you that an ATB update will remove the repairs that you made to the non-Creo models in IDD because these modifications are not Creo Parametric changes.
When you convert the non-Creo models to Translated Image Models (TIMs) in Creo, the TIM parts and part components replace the non-Creo part models and part components of the assembly models. The conversion of the non-Creo part models to TIM parts and part components transfers the bodies of the non-Creo part models to the TIM parts and part components. You can then make the following part and body-level changes to the TIM parts and TIM components and apply the design changes to the non-Creo part models:
Add bodies to the set of multiple bodies in the TIM parts and components.
Remove a subset of bodies of the TIM parts and part components so that the TIM parts or components become single-body models or remain as models with a reduced number of bodies.
Remove all bodies from the TIM part or part components so that the TIMs do not have solid geometry.
Add material to the default or the user-designated body of the TIMs.
Add or remove the open and closed quilts from the TIM parts and components along with their bodies.
Intersect a part component containing solid bodies with assembly-level features such as rounds, cuts, and holes.
Include part components with multiple bodies in the assembly as flexible components.
Remove the intersection or flexibility of a part component that contains multiple bodies.
As the TIM parts and part components are ATB-enabled after you converted the non-Creo models to the native TIMs, you can associatively update the TIMs so that the addition and removal of solid bodies and quilts are propagated to the source non-Creo part models.
