XYZ Function Surface, Globoid creation no longer working (just produces a point like object)
It is working correctly in 2.79b, it was working in the 2.80 release of about last February but is not working in the current (July 2019) release of 2.80 nor in 2.81 Beta nor 2.82 Alpha

X : - (29 - 23 * cos(u * pi / 6 - 0.0183)) * cos(u * pi * 8)
Y: - (29 - 23 * cos(u * pi / 6 - 0.0183)) * sin(u * pi * 8)
Z: - 23 * sin(u * pi / 6 - 0.0183)

This is not a bug in the addon.
The addon creates the desired grid, but it does not appear in solid mode. Faces are zero size.
To avoid further questions, I added a display of the created object with wire enabled (a custom option).
