  Nope, it rotates it around <0,0,0>.

  If the first point is located at <0,0,0> then that's true. If it's somewhere
else, then it isn't (is it will always rotate around <0,0,0>).

:  How can I make a prism object and if I apply the
: rotate parameter have it rotate around the center of the prism object?

  What is the center of a prism?
