Are anybody can help me with proper designing of pointed segments from the photo in attachment for later nice sheet metal drawing-forming in real manufacturing
Thanks in advance.
Your part can not be deployed if it is a part punched.
It is possible to model the part but not to get the exact unfolded form including the hole since the hole is only when punching.
From what I see, you'll need a sheet metal forming tool. Go to the tutorial "shape tool"

Creating the all shape in SW sheet metal will ad additional complications, I have been try with Indent function but is not appropriate if the part is with cutoffs (holes). Creating later cutoff after Indent is not giving real situation for flattening.
