Element: entity.extents[2]
Element: entity.extents[2]point
The 3-D extents of the graphic primitive. This element has two point values: the minimum X,Y,Z and maximum X,Y,Z of a box enclosing the primitive. This element is maintained by the system and cannot be redefined.
For primitives with actual height or pixel height dimensions, e.g. nodes and glabels, such heights are ignored and only the origin of the primitive is used during extent calculation.
