Imported models can be used in synchronous modeling. Imported models contain no feature definitions. These models are a collection of faces that only describe the model shape. In order for these models to take full advantage of the synchronous modeling and edit behavior, tools are provided to recognize specific faces and arrangement of faces. These recognized faces covert to synchronous features. The converted features behave the same as if they were created in the synchronous modeling system.

Use the Recognize hole patterns command to detect hole patterns. The command is disabled if the file does not contain hole features.
