Though bend relief lengths and widths vary between projects they all share a common goal.
You can add a corner relief to a single sheet metal body.
Enter relief size by bend radius ratio or force bend reliefs.
In general a minimum bend relief is equal to the material thickness plus the inside bend radius.
To eliminate this a bend relief is added so the edge of the sheet metal is perpendicular to the bend.
Click corner relief sheet metal toolbar or insert sheet metal corner relief.
Click the create relief tool button on the sheet metal ribbon tab.
For example if you make a partial flange as above using all the defaults the software makes relief cuts at the end of the bends as shown to the right.

Synchronous sheet metal is pretty cool even cooler than just normal synchronous modeling if you ll excuse that word.
Do one of the following.
Preventing tearing and part deformation during the bending process.
Under corners click collect all corners to list all corners in the sheet metal body.
