apply curve on surface!

[AC Design]

Good morning, everyone!
well found! (I don't write time... )

I'd have a little problem, drawing a diadem, something new for me, and I have a technical problem. .

As an attachment, I have the curves applied on surface No. 1 which should be applied to surface No. 2 without any modification or stretching or anything else...

How can I do that?

thanks in advance to all those who will want to answer!

I forgot to say that I tried with the _flowalongasrf command but without result. . .

I don't know in rhino, but if you attach the file in dwg format, you can take a look at it. or dxf, if you're blind, of course!

I'm afraid there's no way to avoid ironing and deformation, and it couldn't be otherwise.
On the other hand, that is not the right method to approach this command (_flowalongsrf).

first draws on the surface 3d the external shape you want to give to the diadem (with the right measures that must have) and then with the command _createuvcrv put it on the floor.
only at that point you can draw the inner lines of the diadem, being sure that then the _flowalongsrf command will position everything exactly on the 3d shape.

Good morning... and thank you all for the answers.
Unfortunately the roblem is precisely to bring back the right silhouette of the object on surface 3d.

I tried the _flowalongsrf command just for a board you gave me a long time ago... but without a result... I'll have to invent something.

thanks in advance,
alessandro.

Bye!

Here's the file...

thank you for your interest.

I don't have much time to devote to you today, even if I don't think of easy solution, anyway I try and then I put the result on you. Okay hello and thank you!

thank you!

I look forward to it.

Meanwhile I am trying various alternatives...I have grouped the curves and, I have moved them on the quadrant of the surface 2 and, with the command " fold ", I am applying it to the piece piece surface...as if the same brooching....the result leaves a little to want... but at least I have a pity...continuous to try. . .

I did a quick test....:smile:

Since the superfice that simulates the human neck is a "splantable" surface as it's a single curvature, I used the _unrollsrf command.
on the superfice "planned" I positioned the profile of the diadem and I "stated" it with the _cageedit command to better fit into the silhouette of the surface.

at that point I could apply the _flowalongsrf command, using as references

1 - "planned" surface
2 - 3d surface

the measurement difference between the 3d curve and the starting plane is about 16.5 mm.
better management of cageedit is possible to reach very minor differences.

ps: but I would design the diadem on the superfice "planned" and not on that generated by the command _createcrv.
In this way I would have a greater correspondence between plan and 3d

the result seems to be really good.... now I do some evidence and let you know. . .

You were priceless!! Thank you very much.. .

I wonder why I had associated the word diadem to a crown, not to a collar!
in any case thanks to the right mariuss.r; nice story to know that rhino does this manipulation of the image. would it be useful to find the tutorials of these commands?? No idea?

 

[Ezio Olivato]

this is my proof of construction, but it is not minimally comparable with the potential of rhino!
for the procedure I regulated myself in this way:
1 extrusion of the profile curve;
2 creation of a ring of the diameter of the collar;
3 intersect command between the two solids.

you have perfectly rejoined in fact... but this must be brought both as choker... and then collar, and as diadem.. .

Here you are the result after several attempts, more I do not know what you could get with autocad.
hello and good day
