Hi,

Use the "Sheet Metal Styles" tool in the tools browser. Under the Bend tab the "Bend Radius" is set default to sheet thickness, change this to your specific bend radius. You can allways override the default bend radius to have multiple bend radii in your sheet metal part by changing the bend radius when using the different bending tools. In all bending tools there is a box to change the bend radius. Hope this will help you.

Cheers
