48 | -- owner OwnerId, and the coordinates Xmin, YMin, ZMin, XMax, YMax, ZMax. |
49 | -- Xmin, YMin and ZMin define the minimum point in |
50 | -- the front lower left hand corner of the box, |
51 | -- and XMax, YMax and ZMax define the maximum |
52 | -- point in the back upper right hand corner of the box. |
