rotation of surfaces

[lorenzo83]

Hi, I have a problem that I don't know how to solve with catia v5. I have a geometry consisting of non-symmetrical 3d surfaces and I have to rotate it around an axis. what I want to have is the external geometry obtained with rotation. i.e., I'm not only interested in the initial and final geometries, but all the envelope. I have no symmetry axes so I can't get the section and then make a revolution.

to trivialize, you can think of a cylinder built along the x axis that must then be rotated around that y between -10° and +10°. I do not want the initial and/or final cylinder but the "ventor" between the two corners.

Is there a way to achieve this in the casket? At the moment I am trying to recreate the surfaces manually by connecting the base geometry and that rotated with spline...but the result is not at all beautiful.

Thank you for your help.

You mean something like that? .

Hi.

Hello, thank you very much for the answer. So, I don't care about the intermediate cylinders, the first and the last... what I need is the envelope of the external surfaces that connect the original geometry and the rotated one... I don't know if I explained. Now I try to make an example from your file.

So what like that?

In this case everything works until the rotation axis intersects the section of revolution.

Hi.

the problem is precisely that the surfaces intersect... I did a test with the cylinders, I reconstruct in yellow what more or less I would like.. .
