generate cruva-guided by sweep

[telefunken]

Hello, everyone.
It's the first time I've been writing on this forum, although it's been recorded for a long time.
until today I have received much help reading the posts of the various users, however today I am asking for help to you.
I go to the sodo: in the following image I have to "build" the two arches of reinforcement badly marked with red ellipses


I think they're to be done with a sweep.
Now..what function to use I think is there last of my problems. Instead I just can't figure out how to generate the curve-guide. the problem arises from the fact that the objects in question develop on 3 different planes, and therefore it is not possible to work on one floor at a time, to create a special plan.
building a piece at a time with the right curvatures I think it is improposable (or at least a Chinese job).

I ask you some help.. ideas?

thanks to all those who will help me:finger:

I obviously don't have the pallidest idea of the final shape you imagine and then how it should be your driving curve, but having to work not on a plane, you tried with the spline in the 3d shizzo? If you do some support geometry, always in 3d sketch, you should succeed.

cocncord, or spline3d, or some very large spiral piece.

..uhmm. Nice fork. I don't remember now, but maybe it's for yamaha? :smile:

Anyway. .
creating those paths is not a problem, you do it quietly with the sketches3d.
However, I do not agree with the spline and curves "strane" in this case; in "carpenteria" it is better to stay between lines and arches. stuff that can be traced, quote, interpret, measure and build easily with simple forms. then for this particular you have more than enough: View attachment FORCELLONE.raras I told you the paths for the sweeps of that "capriata" are made in sketch3d, and all with lines and arches.
everything is very indicative and schematic, but without having the real dimensions I went quickly to the eye.. I hope I made the idea.

greetings

support sampom. in this application with the sweep from how to guide a 3d sketch.
