As I have been getting familiar with SW sheetmetal capabilities, I noticed something on one of my recent parts.

Attached are two jpgs of a closed corner.  In the model you can see the flange edge has been extended, on the drawing you can see it's just straight.  Shouldn't there be some added stock on the flange of the flattened part as hand sketched in red?

Wondering if I forgot to turn on some option or something?

This flat pattern I would think would result in open corners by roughly the bend radius?

Running SW 10 SP 0

Any help you can offer would be great!  Otherwise quite impressed with the improvements to SW 10
