S bend on profiled tube

Yann_Roth_91Yann_Roth_91 Member Posts: 7 ✭✭
I am trying to model the S-bent tube from this drawing : 
I tried to first define the bend path and made some profile along the way to connect with a loft function without success. I thinking it would be easier to first make the straight tube and then apply the bending but I don't know which feature to use. I tried with metal sheets but it doesn´t look like the right tool for this example.

Thanks in advance

    Modeling a solid tube is not that complicated....however the inner hollow is another story.  Seems like the drawing is missing some critical info to accurately model the "hollow".

    Two separate lofts, one like John shows you above, to define the outside, then another that you subtract from the first. And yes you will need all new profiles, but might get away with using the same path.
    Good luck

    That drawing is very odd. It seems to be more schematic rather than to scale. I would have a very hard time interpreting where all the bends are. The wall thicknesses are not to scale at all.

    It would be very hard to read if to scale considering the lengths and thicknesses involved. Hopefully, humans are capable of abstraction.

    Considering the original drawing is missing critical dimensional details of the inside profile it is impossible to model the hollow accurately.

    You can guess at the inner profile, or like Puck mentioned, "abstract", ...but if that is the case, might as well use a simple Shell operation instead!  The end result will be as good as any guess one would make.

    @Puck To the OP...if that is not acceptable then further dimensional details must be obtained.
