A surface value as one of the parameter of closed curve


New member
I have to design an S-bend duct and I need create couple cross section of this duct, but I need maintain the value of surface of this cross sections.
Does anybody have some experience with this??

Do you want to maintain the cross sectional area?

Will you make this S-shape as one duct or several ducts?

Are all the cross sections rectangular? A picture would help us understand better.
