Rip corner seam on converted part edge

The Corner Seam Rip option is useful in a limited number of cases with part models converted to sheet metal models.

Note: Be sure to have a uniform thickness model following your conversion and that this thickness equals the material thickness defined in your active Sheet Metal Style.

1. Use the Corner Seam Rip option to open an edge between faces that you later use to flatten the converted part model.
   Note: The resulting open corner typically leaves material that must be removed.
   
2. Create a sketch and manually remove the material using a Cut.
   
3. Following the cut operation to clean out the remaining corner material, use the Bend command on the inside edges of what would have been modeled as flanges.
   
   Note: Bends are typically best placed on inside edges.
4. Once you rip and clean up all corners, and manually apply bends, you can flatten your model.
