solid-superfici mixed modeling approach advice

[gp1nick]

Hello everyone

I have to design a mtb (the orange bow) element, adapting it to other purpose in the automotive sector.
having never drawn such a form, and being accustomed to working with solids, I am stretched on the connection of the 2 legs. that bow is very difficult to carry with a decent shape, so I wondered if it should be done with surfaces. I tried various solutions, even with freestyle, but I don't come out.
the last idea is to try to make a blend of various sketches

leaving the reinforcement brackets/ribs that in my case will not serve, how would you approach in the connection of the two legs?

3-4 drawings section sketches in strategic position and create the arc with a sweep.
It seems to me the strategy that guarantees the greater possibility of parameterization and agile modification in the future.
But I'm not an experienced modeler. .

as a command you can use (you must) "blend of sweep" . i.e. driving curve and multiple sections in the points you think of geometry control. (as already suggested by stan9411)
when things are a bit complicated I prefer to use "surface union" with the option close ends and solidify after. the surface union with closed ends in 90% of cases allows you to have the same commands as solids, but you are unscrewed by them. It's kind of a multibody.

Thank you very much, I made some attempts. In practice I did a sketch curve with intersections to get my 3d curve, then on planes put in normal position at the curve in various points I realized sketches with the same geometric profile (simil-rombo) but with odds slightly different from each other. I have combined surfaces, closed extremities and solidified but what I get I make a great effort to use it with roundings and other extrusions, I create seems to have problems intersecting parts

Once you have built your basic architecture (guideline and reference sections), the command “blend sweep” already generates a solid feature. it is an infinitely less stable way to model .. tant is that then you can't make a connection

I agree with stan9411 you don't have to do surfaces and join them, but the command "blend of sweep" does everything, if you want a advice in the sketches that you will go for the various sections do not insert the fittings, those do them after

@gp1nick it would be nice to know if the advice was helpful and maybe to see the result....

I unfortunately lost myself and I entrusted to others the assignment, I had passed the delivery time. in my spare time I promised to deepen my speech and maybe do some private lessons with some professionals. . thanks to all for advice, I definitely learned something extra

only one note on the method... I would say no. just work with surfaces, whether they are features of extrusion, revolve, or sweep blend does not matter. to the end go with the Booleans (merge, trim, etc...) join everything in one surface and try to solidify. if everything works without errors then it means that the modeling went to good end.
