You can create a folded model view and a flat pattern view for a sheet metal part or iPart (The Flat Pattern option is available only if a flat pattern exists in the source file.)
Sheet metal annotations can be created only in flat pattern drawing views.
The following apply for sheet metal iParts:
- When you create a drawing view for a sheet metal iPart, you can select an explicit iPart member on the Model State tab of the Drawing View dialog.

- To update an out-of-date iPart member, select the member on the Model State tab of the Drawing View dialog.
- To reference a specific iPart member instead of Active Factory Member in a legacy drawing, edit the drawing view and select the member on the Model State tab of the Drawing View dialog.
