Found the answer:

- 2147.483648 to 2147.483648 for both planes is the range.

Note: if your 2d object exceeds the positive number, it becomes negative, for the plane X Y in question.

Also note, that this only happens when the +max is exceeded, not in negative direction.

If it is exceeded in negative direction, it becomes 0.

Ill create limits as needed.

This is just an observation, not a requst for any changes.
