Full Version: Organically curved Ring bezel

Show messages: All  1-6  7-13

Hi Gunter,
perhaps this method will give you what you want.
1) create 2d front profile and side profile as shown in photo.
2) extrude.
3) boolean side profile.
4) fillet inner of ring.
5) fillet outer and add fillet set to taper down to head.
6) remove these fillet surfaces and then loft to give chamfered face.
7) fillet these edges as required.
Hope this helps.
Cheers
Barry

Hey Michael,

Thank you so much for your explanation, this is very helpful!

I did what you suggested and have made some progress but am now a little stuck. I managed to create this:


The problem is when I use the blend command, it creates a bulge:


And to complete the adjacent sides, I created another curve and extruded it:


I can't figure out how to properly (and elegantly) intersect the extrusions and form a solid.

Thank you for your brilliant support!
Gunter

Hi Barry,

Thank you very much for your input.

I tried what you suggested and managed to create similar results, but I am unable to create the 'facets' by filleting. Could you please let me know what I'm doing wrong?

Many thanks!
Gunter

Hi Gunter,
try these curves.

Hi Gunter

if you generate these curves and sweep surfaces for all of the sides , you can adjust the curves to get the shape you like, every point junction must be exact to get a solid.

then join the outer surfaces and planar top and bottom to make a solid which you can can cut

Hi Gunter,
I have modified my method so using fillet to cut the ring to form the facets is not required.
The extrusion and boolean is the same but have added some trim curves then the edges are lofted etc.

Sorry i have not seen that was a 3DM !

So same method with the Rail Revolve (possible because same Top and Bottom profil )

Then View Points and move bottom pts horizontally to the ring

Take these new surface Top Bottom Face / Planar

You have a solid

Applyy any boolean DIff with trapezoidal profil if wanted (not made here)

Boolean Merge with The Ring (ring)

You have some draft variations for explore that you want...
