Plotting a Sphere under Mathcad Prime 2.0

[JohnDoe]

Dear Mathcad fans,

I would like to plot the sphere with the equation x^2 + y^2 + z^2 = 16. When i choose 3d plot and put the equation mathcad generates an error. can someone show me how to plot the sphere in Mathcad prime 2.0 ?

My aim was to plot the section of the above mentioned sphere cut by the planes y=0, z=2, x=1 and x=-1.

Any idea how to get that in Mathcad prime 2.0?

It's easiest to plot a sphere parametrically as a function of r and theta.
