Hi @w64bit
EXTMIN stores the lower left of the extents while EXTMAX stores the upper right extents of the drawing 🙂

The OP is asking about the third dimension, guys.
That's there, too, in the third number in the value of each System Variable.
Be aware that if the drawing changes in a way that pushes either extent farther outward, the values of EXTMIN and EXTMAX will adjust accordingly. But if it changes in a way that pulls the extents inward, such as by Erasing or Moving or Scaling down something(s), their values will not be updated until a ZOOM All/Extents occurs.
