How to smooth out transitions between solids? - Joints between swept and extruded and lathed solids too noticeable

Hi,

I swept a one rail solid with a twist and then, at the ends of the solid, I created an extruded solid and a lathed solid using the end profiles of the first (one rail swept) solid.

The resulting three part solid, after boolean, should be smooth throughout.

But there are visible joints. How can I smooth them out so at least they are not noticeable to the naked eye? Please see the attached picture.

Thanks.

From what I read in your post, if I understand what you are asking, there is an upper section and a lower section that you want to have blend together by a 3rd section?
Did you try a "loft with a guide curve"? You will need to figure out how to manually align the guide curve(s) to be tangent or curvature continuos, "touching the end of both sections",
ideally at a point on the end of the section. You might need to get a curve from the end of the sections by, if I remember correctly,"explode a curve tool(?)".
Then use the "loft with guides" tool to transition the shapes. I don't know of an easier way right now.
Good luck!

Yes, Tem, you understand the problem correctly. I did try skin surface with a guide but the result was slightly wrinkled in spite of having the superfine resolution on. Your proposed solution looks promising - I'll give it a try. Thank you for taking the time to help!
BTW - I wonder if this is a good example to apply subdivision modeling to. I have not learned that yet and I am looking forward to more tutorials and a user guide.

Attached is an image using the Lofted Solid tool. You can use the Inspector to set the bulge factor which controls the magnitude of the tangent vector from each take off face. This is G1 continuous only.

As Tem mentioned for further control you can use a guide curve between the shapes.

Note this tool is found in the the Solid modeling utilities. (not surface/skin tools)

Great - thanks, Tim.

BTW - Between Shark FX v9 and Keyshot5 Pro on my Mac I have completely freed myself from Windows and Bootcamp. With those two great tools I can do all I need without Modo and Windows only IronCAD. Thanks for making Shark available for the Mac, and for adding subdivision modeling.

Thanks Mark, the positive feedback regarding Shark is most appreciated.

Hi, I only have a minute here. Sub-Division modeling is a possibility for your project, but if the shape of the cross section is important, then it is probably better to use the solid/surface tools.
