Hello All,

Long time listener, first time caller.

While I have used C4D on and off for a few decades I have not done precision modeling in it.

I’m trying to find the cleanest way to add rounds to curved edge. I have enclosed an image as reference.

The area I’m trying to round is the transition from the curved cap to the sides.

Hi Alex,

I have sent you an upload link. A screenshot gives me a little bit of information, but not a lot. How much you can round these edges is highly dependent on the given geometry. Except, of course, you use the Volume/Mesher option.

All the best

Thanks Dr. Sassi!

I uploaded a the file.

It started as an illustrator file but I’m thinking that re-creating in C4D could produce a cleaner model.

Looking forward to seeing your solution.

I’m also playing with Sub-Ds… they just go against my tendency for CAD like precision.

Hi Alex,

Thanks for the file.

I adjusted first the number of segments on the sphere, then the Spline interpolation.
This gave a less dense result.
The Boole was set Single Object> None.

Then the Current State to Object was used.

The resulting Sphere Cut was all I was after. Points too close to each other are treated with the Weld Function.

The Sphere surface was then extruded on edge. In a few small steps.
The last one very small (0.01) and then moved along the Z-axis to create the volume. The Z value [size] for this selection was then set to zero to make it flat.
A few extrude steps to create a solid edge and Fill Polygon Hole to finalize this step.

The N-Gons left on the surface were handled with the Spline Edge and Knife Tool.

After all, a short Optimize function was used.

The SDS (subdivision surface) works now reasonably good. A CAD precision can’t be given here, as the would require a mathematical approach, as given in most CAD apps, and the precision is then broken when you go into polygon mode. I will not even pretend or motivate expectations into that direction at all. But I you know that of course.

Thanks!

This looks great. I will take a look at it and come back with any questions. Extruding the edges out was the key piece I think I was missing.

Thanks a lot, Alex.

As usual, I try to provide an alternative or other options to do that. After I used your file, I like to share how I would start this purely in Cinema 4D.

Please have a look at the one minute screen capture (no audio). Screenshot and project file

I think that is faster than anything else I can think of.

Cheers

Thanks!

This is a very elegant solution.

I will see if it fits in the rest of the process. I will probably post more questions

You’re very welcome, Alex; thanks for the feedback.

If there is another question, please let me know.I’m happy to look into it.
I will leave the upload link open for now. If any file is not for the public, please add private in the name, thanks.

Have a great weekend.

P.S.: please check your Cineversity PM, the file is linked in the PM.

Cheers
