multi body loft with guide lines

Good evening to all,
I'm creating a model that comes from rhino in solidworks trying to parameterize it.
the rhino model was made in 4 bodies that are subsequently merged to create a single body, so I thought to recreate the same strategy in solidworks using 4 lofts and then use the matching command, what do you think of this strategy? Do you think it is correct to proceed like this? or would it be more correct to create a single body and proceed with a sweep/loft cut to recreate geometry?
what strategy would you have adopted?1634832365661.webp1634832660185.webp1634832681628.webpI used the first strategy and creating sketches on the sections of the 4 bodies, which I carried out on several parallel and translated planes of a certain distance by copying the profile of the original body.
to recreate the bodies I used the loft command and used 3d sketch to create guidelines
(the body is complex and I had to use arches that I created on the floors that pass for 3 points of the consecutive sections inside the 3d sketch, not wanting to use the spline specially).
the result however is not satisfactory since the body is not perfectly clean but seems to be "indented" :)
I am in front of this problem and I wanted to ask you some advice or point of reflection to reproduce the body in a "clean" way:
1) the problem of the guidelines on the loft comes from the fact that the arches used to connect the sketches of the consecutive sections, lie on non-complanar planes, therefore I cannot make the arcs between them tangents in the intersection point. so I would ask you if you know a way to use this method by inserting the tangences on the curves correctly (as it is not possible to follow the desired profile and create a single plan for the profiles)
Loft con piani differenti.webp1634830718140.webp1634830779962.webp2) I tried to remake the guidelines with the command always spline on 3d sketch and the result is definitely better, only that I can not parameterize them in a unique way, how do you bind the spline within 3d sketch?

3) surely method 1 is the most complex and even longer, you when you find yourself in these situations as agite? Would you give me some advice? (I also tried to make guidelines only on the main planes and making plans tilted by the origin of the system not getting the desired result)

Thank you in advance for your time

import the rhino file, after turning it into part of course, and with that as a base build sections and guidelines.
if you cannot do this a method to manage the guidelines made with 3d sketches and to create anchor points (using the plans of the various sections of the profile).
in this way the guideline is bound in precise points without going mad with the constraints of the 3d environment, which on the curves are complicated, the curves must however be all tangent between them; by changing the support points you can manage the profile without having to enter the various sketches making the profile management more immediate.
if you try with this system I suggest you make a pattern of the various sections on a sheet and then rename all the elements of the tree so you have clear where you are working

I'm still waiting for the answer to your question modeling on curved walls edge, there would be others, but they're too old and there's no point in getting them back. when opening a discussion is good rule to give feedback to the received
 
Thanks @massivonwiezen in the week I do a modeling test by taking advantage of your advice and show you the results.
Thank you very much
 
Defintivo Ribassato.webpLaterale Uff Tec.webp Hello, everyone.
I explain how I made the model:
I first saw how it was made with rhino.
the procedure was to create 4 solids with loft
I did similarly with sw.
I solved the problem of driving curves using a 3d spline.
in this sense I had to do various tests, or decide until what section
you had to extend the spline; from that point on I just did
a 3d line and then given the tangency bond between the two.
at the end the result was very similar and the safeguarded concepts
