how sphere is unfolded in sheetmetal and how the profile is created on unfolded portion and again is folded. Because it is not having any bend portion thats why it is not unfolded.
Thanks peter for your reply, I just make a quarter circle and revolve it but it is not having any bends so it is not unfolded. But now i found my answer. I have to create a single portion of the sphere and then proceed to the circular pattern. I think it works for me, I am working on it.
I take it's a theoretical exercise or that you don't mind it having lots of bumps and ridges due to lots of welding beads or... that those or someone else's problem to get rid off.
You want an entire sphere made out of one piece in sheetmetal?
How do you imagine that being possible?
