Join sheet metal faces using a Bend feature.
Bend features can join sheet metal faces that were created in a particular location to meet specific design criteria. When you select edges on sheet metal features, you add material to the model using the bend radius and material thickness defined by the sheet metal style.
Faces extend in compliance with your default (or selected) bend radius. If the faces are parallel, but not coplanar, you can add a double bend. Depending on the distance between the faces, the bends are trimmed so that they are tangent, or a face is created between the two bends.
A single flange or contour flange feature in a sheet metal part can contain any number of bends.
You can override default sheet metal styles from the Bend dialog box as you create your sheet metal bend. These settings include how the flat pattern unfolds, and the bend relief settings between faces.
