spring with curved axle

[MARCOC]

Hello
someone knows how to draw a spring that has invenc to have its axis a right lia has by a central axis an arc.Result to have a helicoid that if it happens on a circle. .

thanks to all

(I'm sure there's something like this on the net but I don't remember where)

guard qui:http://www.cad3d.it/forum1/showthread.php?t=15726&highlight=molla&page=2But it seems to me that with inventor you can't do it, or rather there's no special command.

inventor does not have a specific command, as tarkus rightly says, but I tried these two methods:
in the first I built it geometrically, in the second I used the fold command that I think playing a little with the values could give good results....
take it as a starting point for further lucubrations

Hi.

great diegus:finger:

Nice idea to incorporate a cavity into a body and then be able to bend it.
But one thing I can't do, even because I never use the "sculp" command:
the command asks me of the surfaces; in your file I see that they are given:1 and 2= the surfaces relative to the initial and final plane of the folded square profile, 3= the compound relative to the surface of the helid.
How do you pull out this compound that doesn't come to me?
I tried it out of the blaze command but it doesn't make me choose the surface of the helid.:frown:

Thanks tarkus, it's a pleasure.
you must use the object copy command and select the internal faces of the helid. Unfortunately I couldn't make this surface associated (I don't understand the problem), so if it changes the fold then it doesn't change the inner surface.
I'm working on it, if you think of anything... .

spring on curve_1 what is it, a chip of an eccentric turning ?:biggrin:

Bye.

:finger: thanks for the tip.
I was a little forgotten about the copy command. I used it to do the derivative parts once, but since there's the specific command I never used it.
I also saw that it doesn't work. bho, you'll be studying up.
rather, I saw a problem:
cutting the spring with a perpendicular plan to the object bending axis, I saw that the section of the spring wire is no longer regular, the more you turn away from the bending center and the more elliptic.
But if the curved spring serves for a need for representation, I think it can go well the same, otherwise you have to go to the sweep on 3d sketch as in your other example.

I think the problem is that all plans and points have been built "outside" by the 3d sketch, try to do them internally to the sketch, and maybe they will be "adactive" to the change of the bending radius. . .

great,:finger:
missing only to take the correct parameters and "bind" them to a spreadsheet
to have a + fast parameterization. . .

I'll compliment you.
You don't miss the fantasy.
