This question was asked during the live webcast:
Q: Is the model used in this demo an original model, or an imported STEP model?

A) This model was imported from Catia v5. In the aerospace industry, we see quite a bit of Catia imports, and they have certain idiosyncrasies, such as all the holes come through as split holes. So the techniques we used can be very helpful in straightening out geometry like that. By “optimizing” the model, we get single cylinder faces, as an example. Blends are sometimes represented with additional faces as well, and re-blending to the same size will reset them to single surfaces.
Of course we can import IGES, STEP, DWG, and other file types as well. The slide we showed at the beginning listed all of the file types that can be imported:

This question was asked during the live webcast:
Q) If I import a STEP model, will I have the same control over the model?

A) We showed several types of simple “Synchronous Modeling” optimization changes, but there are pretty significant capabilities even beyond these, that you can use on any type of model, including imported models.
Not only can we do simple things like delete or extend faces, and re-size blends, we can also re-order features in where they occur so that we can make other changes to geometry. This lets us get beyond just the topology of faces, but really lets us establish “parametric” relationships even at the topological level with synchronous technology. So there are pretty deep model preparation capabilities with these synchronous tools.
