entity group codes by number
group code description
-5
app: persistent reactor chain
-4
app: conditional operator (used only with ssget)
-3
app: extended data (xdata) sentinel (fixed)
-2
app: entity name reference (fixed)
-1
app: entity name. this changes each time a drawing is opened. it is never saved. (fixed)
0
text string indicating the entity type (fixed)
1
primary text value for an entity
2
name (attribute tag, block name, and so on)
3-4
other textual or name values
5
entity handle. text string of up to 16 hexadecimal digits (fixed)
6
linetype name (fixed)
7
text style name (fixed)
8
layer name (fixed)
9
dxf: variable name identifier (used only in header section of the dxf file).
10
primary point. this is the start point of a line or text entity, center of a circle, and so on.
dxf: x value of the primary point (followed by y and z value codes 20 and 30)
app: 3d point (list of three reals)
11-18
other points.
dxf: x value of other points (followed by y value codes 21-28 and z value codes 31-38)
app: 3d point (list of three reals)
20, 30
dxf: y and z values of the primary point
21-28, 31-37
dxf: y and z values of other points
38
dxf: entity's elevation if nonzero.
39
entity's thickness if nonzero (fixed)
40-48
floating-point values (text height, scale factors, and so on)
48
linetype scale. floating-point scalar value. default value is defined for all entity types.
49
repeated floating-point value. multiple 49 groups may appear in one entity for variable-length tables (such as the dash lengths in the ltype table). a 7x group always appears before the first 49 group to specify the table length.
50-58
angles (output in degrees to dxf files and radians through autolisp and arx applications).
60
entity visibility. integer value. absence or 0 indicates visibility; 1 indicates invisibility.
62
color number (fixed)
66
"entities follow" flag (fixed)
67
space--that is, model or paper space (fixed)
68
app: identifies whether viewport is on but fully off screen; is not active or is off.
69
app: viewport identification number.
70-78
integer values, such as repeat counts, flag bits, or modes
90-99
32-bit integer values
100
subclass data marker (with derived class name as a string). required for all objects and entity classes that are derived from another concrete class to segregate data defined by different classes in the inheritance chain for the same object.
this is in addition to the requirement for dxf names for each distinct concrete class derived from arx (see "subclass markers").
102
control string, followed by "{<arbitrary name>" or "}". similar to the xdata 1002 group code, except that when the string begins with "{", it can be followed by an arbitrary string whose interpretation is up to the application. the only other allowable control string is "}" as a group terminator. as noted before, autocad does not interpret these strings except during drawing audit operations; they are for application use.
105
dimvar symbol table entry object handle
210
extrusion direction (fixed).
dxf: x value of extrusion direction
app: 3d extrusion direction vector
220, 230
dxf: y and z values of the extrusion direction
280-289
8-bit integer values
300-309
arbitrary text strings
310-319
arbitrary binary chunks with same representation and limits as 1004 group codes: hexadecimal strings of up to 254 characters represent data chunks of up to 127 bytes.
320-329
arbitrary object handles. handle values that are taken "as is." they are not translated during insert and xref operations.
330-339
soft-pointer handle. arbitrary soft pointers to other objects within same dxf file or drawing. translated during insert and xref operations.
340-349
hard-pointer handle. arbitrary hard pointers to other objects within same dxf file or drawing. translated during insert and xref operations.
350-359
soft-owner handle. arbitrary soft ownership links to other objects within same dxf file or drawing. translated during insert and xref operations.
360-369
hard-owner handle. arbitrary hard ownership links to other objects within same dxf file or drawing. translated during insert and xref operations.
999
dxf: the 999 group code indicates that the line following it is a comment string. dxfout does not include such groups in a dxf output file, but dxfin honors them and ignores the comments. you can use the 999 group to include comments in a dxf file that you've edited.
1000
ascii string (up to 255 bytes long) in extended data.
1001
registered application name (ascii string up to 31 bytes long) for extended data.
1002
extended data control string ("{"or "}").
1003
extended data layer name.
1004
chunk of bytes (up to 127 bytes long) in extended data.
1005
entity handle in extended data. text string of up to 16 hexadecimal digits
1010
a point in extended data
dxf: x value (followed by 1020 and 1030 groups)
app: 3d point
1020, 1030
dxf: y and z values of a point
1011
a 3d world space position in extended data
dxf: x value (followed by 1021 and 1031 groups)
app: 3d point
1021, 1031
dxf: y and z values of a world space position
1012
a 3d world space displacement in extended data
dxf: x value (followed by 1022 and 1032 groups)
app: 3d vector
1022, 1032
dxf: y and z values of a world space displacement
1013
a 3d world space direction in extended data.
dxf: x value (followed by 1022 and 1032 groups)
app: 3d vector
1023, 1033
dxf: y and z values of a world space direction
1040
extended data floating-point value.
1041
extended data distance value.
1042
extended data scale factor.
1070
extended data 16-bit signed integer.
1071
extended data 32-bit signed long.
