"wire frame" model of sphere in 3d

[Martha]

I am trying to make a "wire frame" model of a sphere using the 3d graph with LV5.1. Does anyone have any ideas as to how I could do this? I have been able to get the 3 circles corresponding to the x,y, and z axes, but it doesn't look like a sphere because there is no outer circle encircling the entire structure. Any ideas as to how I might be able to do this?

Thanks!

A very straight-forward way is to take the 3-D example Torus.vi, open the diagram and you'll see a constant set to 3; set it to 0 and you have a sphere!

In the same line as Alberto's answer, look at this tutorial at the Resource Library:
