Godmorning.

Iam having trouble with a part that I wont to convert to sheetmetal and make a drawing with bend annotations.

Converting the part goes fine but the flat pattern is only a "semi-flat-pattern" 2 of the 4 bends doesn't unfold.

I have a 8mm plate and the internal radius is 2mm and the external radius is 10mm and the bend angel is 10 degrees sow everything should be fine.

But how to add the last to bends to make my flat pattern unfold correctly?

Check your first sketch. The distance between the two 10 degree bends is not exactly 8mm and that is why it won't flatten.

Maybe something like this (see attached).

Thanks for the help.

Looking at your part makes me think it is funny how different ways of working in inventor can be.

Do you allways make the complete 2d layout and then add material afterwards? 

Normally I would go directly to 3d and then manipulating (adding/removing) material but seems like that in sheet metal the sketched up part works better for this purpose.
