Twisting a part with another part - Vriller une pièce suivant le profil d'une autre

macdony_denis

Hello,
I want to twist a part Part 1 on the profile of another part Part 4
Thank you for your help.

Bonjour,
Je souhaite vriller une pièce Part 1 sur le profil d'une autre pièce Part 4
Merci pour votre aide.

Deforming a part Part 1 on the profile of another part Part 4

There is no one to help me ?!

Sorry, I've had a look but don't understand what you mean by twist?

Can you make a sketch, even drawn by hand of what you want to make it look like?

Cheers, Owen S.

afraid that OS don't suit for continous deformation of geometry, at least there are no bult in instrument to perform it

@macdony_denis, are you trying to animate one part relative to another? If that is the case, you will need to create an assembly with mates. One of these mates can be an angle mate that you can then animate.

I want to make a Torsion of Part 1 over Part 4

@macdony_denis as I already said in onshape you can't solve this problem because it hasn't instruments for deformation of geometry. I imported this part to Wolfram Mathematica and tried to reach some approximate solution, then imported it back in OS. So here it is. https://cad.onshape.com/documents/58d22502f1cd510fe4f1c0e6/w/c90851000dd5cfca76ad3495/e/1ef639222c39ca2585aa9bb9

Thanks konstantin, but it is not quite good

konstantin_shiriazdanov

@macdony_denisI just digged dipper in internal mesh representation in Wolfram Mathematica, and made something better

Thanks for your help, but how to export to STL file? Is it possible to work on the Mesh1?

konstantin_shiriazdanov

@macdony_denis in OS to export to STL: right click on the part > export > select STL format/units/mesh quality > download.
i think for now OS don't has enough functionality to work with meshes, so if you need this part in assembly or drawing you should convert it to solid-body format, but how to perform it I don't know exactly

macdony_denis

@konstantin, Thanks, but how to convert to solid Mesh1?

macdony_denis

How to download the Mesh1 file? Thank you.

konstantin_shiriazdanov

@macdony_denis don't know how to convert it to solid and to export mesh from OS but here the link to the original mesh - https://yadi.sk/d/JeXRO4z63GHWFj
and you should take into account that this is just approximate solution - the deformation law was simle (x,y,z) ->(x,y,z-z')
where z` is coordinate of top surface of Part4. deviation of normal to the surface was not taken into concideration

@Konstantin, I thank you very much for your help. Denis.
