Full Version: Surfaces not tangent or separated

Tricky!

---

Goog idea, Phiro!
However, probably, I'm not skilled as you. So far I need to see the model create piece by piece to undestand where I want to go.
Probably you can see the target before you start...
So I've to model it step by step...

Thanks for your kind contribute!

Hi Pilou,

as I wrote to Phiro, unfortunately your trick is applicable if you already know where you want to go... I never know it :-(
But it opens several doors to me!

Thanks

Maybe SUBD can help in this situation?

---

Michael,

thanks for this explanation... I suppose, so, that I've to use a base form to have a rough form and then work on it to refine to the final model!
From what I can see, a command to extend surfaces is missing, am I right?

Thanks

<< SUBD can help in this situation?
No in optic "already know where you want to go" for have a precision wanted...
as it's always a surprise when you press the SUubDivide button ! ;)

Maybe trim volums Fillets then boolean ... a workflow is to find...

---

Really?
I'll try my right workflow!

Thanks
Marco

Hi Marco,

It is but the method using Flow that I showed above can be used to accomplish it.

Personal workflow when you find it is always the best for you! :)

---

Ok, Michael...

Good!

---

Hope so!
I've to learn tons of commands and their uses.

Bye

Subdiv is maybe not for your case ;)
But can be useful for imagine creative forms!
there are for the moment only 5 principal functions ;)
Native Extrude + special SBridge, SsPlit,Sscale, Subdive
as you see fillet is special ;) And you can't made fillet on the "edges" of a volume subdivided!

Yes, exactly what I mean!
Usually, in Rhino, I draw a circle with the given diameter and then create a form; moving some points I try to achieve the model I need and use the circle as reference. So I try to be nearest to the circle, it doesn't matter of the precision, because when the ring is casted and polished it change its dimensions.
The important things are the setting for the stone that must be precise... but I can use nurbs with standard commands.
So, yes... it's good as you wrote!
I think that, starting from a cube, I can add faces following the guide circle to form a ring... right?

Thanks
Marco

Hi Pilou, first af all big thanks for your fantastic input, much appreciated !
One question: what do you mean by "special SBridge", is this different from
this version:http://moi.maxsm.net/files/scripts/sBridge.v.0.71.2015.03.26.zip
???
Thanks again + best wishes !

sBridge (plugin) is "special" function for Subdivision against "native" Extrude who can be used in certains faces for subdivision! ;)

Yes it's the Max Smirnov one! ;)

---

Many Thanks !

Hi Marco,
not sure if this is the result your looking for but this was produced by using half of the helix (outer diameter of ring).
I extruding it to max depth then trimmed as Michael as shown.
I then shelled it and filleted.
It was necessary to trim the solid where it was going to join in the middle as this was not flat due to the shelling.
I then copied the half revolved it 180 and joined.
Hope this helps.

Barry!!!
That is exactly what I expected to achieve!!!!!!

Thanks a lot

---

Barry,

I follow Michael advises and yours, but... how did you solve the issue in the point where it has to be join?
Mhhh...
In all this job, a profile is missing I think!

Thanks a lot!

Hi Marco,
did you use the shell command (see photo's).
There is no need for a profile.
Make sure to do the filleting on just the half as I had problem trying to fillet after joining.
Cheers
Barry

Yes,

exactly Barry... that face is not squared and it's rotated, so when I copy-rotate the solid, the result is what I've attahced to my post before...
I can't figure out how to solve...
I followed the same yours steps!

Thanks
Marco
