Hi,

In the example you present in the post you can use mirroring to create the remainder of the sphere. [data--> Create Zone--> Mirror] Where are the data coming form and what do you want to do with it? There are several ways to create a sphere depending on the final purpose of the data.

1. Create a circular zone and use data alter to transform the cylindar to a sphere.
2. Download a sphere STL file from grab cad and load it in tecplot.

What are you trying to do and I can point you in the right direction.

Here are the simple steps

1. Create a new layout.
2. Data->Create zone-> Rectangular zone
Set the dimensions to 100, 100, 100
Set XMin, XMax to -1, 1
Set YMin, YMax to -1, 1
Set ZMin, ZMax to -1,1
3. Data-> Alter -> Specify Equations
use this equation: {Sphere} = x*x + y*y + z*z
4. Create an isosurface of Sphere
5. Data-> Extract -> Isosurface

You now have a Sphere in Tecplot.

Let me know how it goes
