Mtext group codes
Group code 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
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
90 Background fill setting:
0 = Background fill off
1 = Use background fill color
2 = Use drawing window color as background fill color
420 - 429
Background color (if RGB color)
430 - 439 Background color (if color name)
45 Fill box scale (optional):
Determines how much border there is around the text.
63 Background fill color (optional):
Color to use for background fill when group code 90 is 1.
441 Transparency of background fill color (not implemented)
75 Column type
76 Column count
78 Column Flow Reversed
79 Column Autoheight
48 Column width
49 Column gutter
50 Column heights; this code is followed by a column count (Int16), and then the number of column heights
