I  have the following problem with bend reliefs in sheetmetal: when I try to bend al five corners at the same time (see first picture) there is a gap  instead of a relief. It is in detail on the second picture. When I bend the corners one by one the effect is even worse. How can I prevent or fix that?

Hi William,

you are seeing the automatic relief created when pulling multiple walls up at the same time.  If you do not want any relief you can create watertight corners.  You can do this by filling the relief in.  Just box select all of the faces and hit fill.  I'm including to pictures to hopefully clear it up.

Regards,
