DXF: X value; APP: 2D point

21

DXF: Y value of maximum limits

12

Insertion base point for this layout (defined by INSBASE while this layout is current):

DXF: X value; APP: 3D point

22, 32

DXF: Y and Z values of the insertion base point

14

Minimum extents for this layout (defined by EXTMIN while this layout is current):

DXF: X value; APP: 3D point

24, 34

DXF: Y and Z values of the minimum extents

15

Maximum extents for this layout (defined by EXTMAX while this layout is current):

DXF: X value; APP: 3D point

25, 35

DXF: X value; APP: 3D vector

26, 36

DXF: Y and Z values of UCS X-axis

17

UCS Y axis

DXF: X value; APP: 3D vector

27, 37

DXF: Y and Z values of UCS Y axis

76

331

ID/handle to the viewport that was last active in this layout when the layout was current

345

ID/handle of AcDbUCSTableRecord if UCS is a named UCS. If not present, then UCS is unnamed

346

ID/handle of AcDbUCSTableRecord of base UCS if UCS is orthographic (76 code is non-zero). If not present and 76 code is non-zero, then base UCS is taken to be WORLD

333

Shade plot ID
