About Retrieving Assemblies
When you retrieve an assembly, you can use the File Open dialog box to select the representation of the assembly to retrieve.
Master representation
Standard lighter representation
Predefined user representation
External simplified representation
On-the-fly creation of a simplified representation
Subset of components
While a large assembly is being retrieved, you can manipulate the model. You can zoom in and out, pan, and rotate the model being retrieved. The final view at the end of retrieval is the new view, not the default view.
