Group codes<br />
Description<br />
21, 31 DXF: Y and Z values of alignment point (in OCS) (optional)<br />
210 Extrusion direction. Present only if the entity’s extrusion direction is not<br />
parallel to the WCS Z axis (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 />
If group 72 and/or 74 values are nonzero then the text insertion point values<br />
are ignored, and AutoCAD calculates new values based on the text alignment<br />
point and the length of the text string itself (after applying the text style). If<br />
the 72 and 74 values are zero or missing, then the text alignment point is<br />
ignored and recalculated based on the text insertion point and the length of<br />
the text string itself (after applying the text style).<br />
