[Solved] Sphere by three points and a radius?

Does anyone know how to draw a sphere by three points and a radius?

I could use some help in figuring this out.

Thanks!

:shock:

I think there is no solution to draw it in a direct way. I guess that designing the circle by 3 points and revolved this contour is the solution...

Hi,

Create the 3 points.
Create a sphere with the desired radius in each point. You can merge the parameter radius of the 3 spheres.
Create a curve intersection between one sphere and the other 2.
Finally create the desired sphere, using as center, the intersection point of the intersected curves. You can merge the parameter of the sphere radius with the other radius.

That's it :wink:
