I installed 2013 Design Suite not too long ago and there appears to be no sheet metal rules - only SheetMetalRules.xml which contains exactly one rule - "Default". I tried install new features through control panel, etc, and even searched the install flash drive - only thing there is same one rule xml file. Isn't Inventor supposed to come with a standard set of sheet metal rules that you can then use to customize? I know 2012 and earlier did.
They now reside within the "Styles Manager". Manage>Styles and Standards>Sheet Metal Rule:
Looks right for a new installation, all you have to do now is RMB on the Default and Save-As copy and create all the styles you need. The nice thing now is when you export your Styles and import into IV2014 it should be easier.
