Hi Shankar Prasad
Sorry iam notwell known aboutthe aerospace sheet metal design but may be it is similar to the Generative sheet metal design
I am confused where you use this flat part, In part workbench or assembly work bench or Use in drawing.
In generative sheet metal design we have cerate a flat part by two mathod
1. By using Fold /unfold button but it is only for visulation,
2. Second process is by using unfolding Button that process discussed in previous discussion.
If you want a one wall is bend or other is flat in on sheet metal part then it is done by using the unfolding button,Select only Bend face (circular face)of the Of wall You want to flat.
following is the image of this type
