The equation of the analytical curve is :u(t)=t & v(t)= sqrt((R^2)-(t^2))-B; where R=2.125 & B=1.875, t=0 to 1. I was able to draw the analytical curve..but wasn't able to rotate it about the X-axis to get the required 3D shape. Kindly let me know if there's a way to do that.

I have attached the curve pic here from CST and the final required pic.
