HI everybody,
When adding a primitive (sphere) to a parametric object, we can see a relationship between the diameter of the circle and that of the profile:
BdyD1=BdyD2 * 0.42 (BdyD2 = 48)
Note also that the diameter of the sphere is equal to 48.05064 and not to 48?
My question is what is the correct equation to get a perfect sphere with the correct diameter?
Thank a lot for any help you could provide for me.
