The following group codes apply to mtext entities. In addition to the group codes described here, see "Common Group Codes for Entities." For information about abbreviations and formatting used in this table, see "Formatting Conventions in This Reference."

Mtext group codes
Group codes Description

100

Subclass marker (AcDbMText)

10

Insertion point
DXF: X value; APP: 3D point

20, 30

DXF: Y and Z values of insertion point

40

Nominal (initial) text height

41

Reference rectangle width

71

Attachment point:
1 = Top left; 2 = Top center; 3 = Top right;
4 = Middle left; 5 = Middle center; 6 = Middle right;
7 = Bottom left; 8 = Bottom center; 9 = Bottom right

72

Drawing direction:
1 = Left to right;
3 = Top to bottom;
5 = By style (the flow direction is inherited from the associated text style)

1

Text string. If the text string is less than 250 characters, all characters appear in group 1. If the text string is greater than 250 characters, the string is divided into 250 character chunks, which appear in one or more group 3 codes. If group 3 codes are used, the last group is a group 1 and has fewer than 250 characters.

3

Additional text (always in 250 character chunks) (optional)

7

Text style name (STANDARD if not provided) (optional)

210

Extrusion direction (optional; default = 0, 0, 1)
DXF: X value; APP: 3D vector

220, 230

DXF: Y and Z values of extrusion direction (optional)

11

X-axis direction vector (in WCS)
DXF: X value; APP: 3D vector

NOTE  A group code 50 (rotation angle in radians) passed as DXF input is converted to the equivalent direction vector (if both a code 50 and codes 11, 21, 31 are passed, the last one wins). This is provided as a convenience for conversions from text objects.


21, 31

DXF: Y and Z values of X-axis direction vector (in WCS)

42

Horizontal width of the characters that make up the mtext entity. This value will always be equal to or less than the value of group code 41. (read-only, ignored if supplied)

43

Vertical height of the mtext entity (read-only, ignored if supplied)

50

Rotation angle in radians

73

Mtext line spacing style (optional):
1 = At least (taller characters will override)
2 = Exact (taller characters will not override)

44

Mtext line spacing factor (optional):
Percentage of default (3-on-5) line spacing to be applied. Valid values range from 0.25 to 4.00.

Xdata with the "DCO15" application ID may follow an mtext entity. This contains information related to the dbConnect feature.
