# Creation of Circle in Space

Hello,

I adress this message to the developpers.

In SalomÃ©, we can create a disc form a vector, a point and a radius.

In one of my codes, I want to select some boundary element. For that, I calculate the orthonormal plane.

So for the selection, I create concetric circles in this plane.

So I know the normal, the center of the point and the radius of these circles.

But I can't find a solution to have the equation of these corcles in the space.

I try with the intersection between the plane and a sphere but it take too many time so create with all the angles which aren't used.

I write to you because you succed to create a disc from a normal, a point and a radius wich is similar to my problem.

Thank you,

Damien H

I just see that you create the circle like I want. But I want the equation or the procedure of the creation.
