Sheet metal rules describe sheet metal part characteristics and how the parts are manufactured.
A named Sheet metal rule (for example: Stainless steel (in) or Aluminium (in)) captures these parameters and applies them by default when you create a new sheet metal body.
Use the Sheet Metal Rules Library to manage shared rules at the hub level and default rules supplied with Fusion. In this design lists rules that apply to the active document.
Create custom rules to match your material specifications. You can also edit, switch, delete, and override rules.
