Group codes<br />
Description<br />
71 Text generation flags (optional, default = 0); see TEXT group codes<br />
72 Horizontal text justification type (optional, default = 0); see TEXT group<br />
codes<br />
11 Second alignment point (in OCS) (optional)<br />
DXF: X value; APP: 3D point<br />
Meaningful only if 72 or 74 group values are nonzero<br />
21, 31 DXF: Y and Z values of second alignment point (in OCS) (optional)<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<br />
100 Subclass marker (AcDbAttributeDefinition)<br />
3 Prompt string<br />
2 Tag string<br />
70 Attribute flags:<br />
1 = Attribute is invisible (does not appear)<br />
2 = This is a constant attribute<br />
4 = Verification is required on input of this attribute<br />
8 = Attribute is preset (no prompt during insertion)<br />
73 Field length (optional; default = 0) (not currently used)<br />
74 Vertical text justification type (optional, default = 0); see group code 73<br />
in TEXT<br />
ATTRIB<br />
If group 72 and/or 74 values are nonzero then the first alignment point<br />
values are ignored and AutoCAD calculates new values based on the second<br />
alignment point and the length and height of the text string itself (after<br />
applying the text style). If the 72 and 74 values are zero or missing, then the<br />
second alignment point is meaningless.<br />
The following group codes apply to attrib (attribute) entities. In addition to<br />
the group codes described here, see “Common Group Codes for Entities” on<br />
