About Machining Process Assembly as Default Model
When the current, default model is a machining process assembly, consider the following:
The DWG MODELS menu option Set State is dimmed except when the current sheet has no views or repeat regions of this assembly.
When you enter a sheet containing views or repeat regions of this assembly, the current, default process state changes to that of the views or repeat regions on the entered sheet.
If you use the Set Model option to switch the current model to a machining process assembly which appears on the current sheet, the system switches the process state of this newly current model to that appearing on the current sheet.
