Update flat pattern extents

Flat pattern extents for sheet metal parts created in R2010 updates each time the flat pattern is edited or reoriented. Flat pattern extents for migrated legacy parts must be manually updated as follows:

1. Open a legacy sheet metal part that was migrated to R2010.
2. Right-click the Flat Pattern icon in the browser and select Extents from the context menu.
3. Click Update in the Flat Pattern Extents dialog box.
4. Click Close.

Note: The Update option does not display on sheet metal parts that were created with release R2009 or later. It does not appear on migrated parts after the flat pattern was updated the first time.
