Solid group codes (continued)<br />
Group codes<br />
Description<br />
22, 32 DXF: Y and Z values of third corner<br />
13 Fourth corner. If only three corners are entered to define the SOLID,<br />
then the fourth corner coordinate is the same as the third.<br />
DXF: X value; APP: 3D point<br />
23, 33 DXF: Y and Z values of fourth corner<br />
39 Thickness (optional; default = 0)<br />
210 Extrusion direction (optional; default = 0, 0, 1)<br />
DXF: X value; APP: 3D vector<br />
220, 230 DXF: Y and Z values of extrusion direction (optional)<br />
SPLINE<br />
The following group codes apply to spline entities. In addition to the group<br />
codes described here, see “Common Group Codes for Entities” on page 60.<br />

Group codes<br />
Description<br />
100 Subclass marker (AcDbSpline)<br />
