First, the Autoscale zoom option seems to always give the ! reply.

Second....

If you try to plot a half a sphere using:

FZ1=sqrt(16-(X^2+Y^2))

This should be a sphere of radius 4. You'll notice these extreme jaggies as it gets close to the plane z=0. At first, I thought it might just be rounding errors, but if you use a radius of 10, you can see the blank areas are much taller in the z direction than 1, which means it's not rounding error. It should be flush with the plane z=0.

Try plotting the following:

FZ1=sqrt(16-(X^2+Y^2))

FZ2=0

That'll plot the semi-sphere and the plane, which gives the following (the semi-sphere should be flush with the plane)...

Perhaps that has to do with the TRIANGLE command, but Wofram Alpha doesn't do much better. for that reason I requested a parametric-3d plot some time ago.
