Common Group Codes for Symbol Table Entries
|
The following table shows group codes that apply to all symbol table entries. Optional codes are shown in gray. When you refer to the table of group codes by entity type, which lists the codes associated with specific entities, keep in mind that the codes shown here can also be present.
Group codes that apply to all symbol table entries| Group code | Description |
-1 |
APP: entity name (changes each time a drawing is opened) |
0 |
Entity type (table name) |
5 |
Handle (all except DIMSTYLE) |
105 |
Handle (DIMSTYLE table only) |
102 |
Start of application defined group "{application_name". For example, "{ACAD_REACTORS" indicates the start of the AutoCAD persistent reactors group |
application-defined codes |
Codes and values within the 102 groups are application-defined. |
102 |
End of group, "}" |
100 |
Subclass marker (AcDbSymbolTableRecord) |
The following table shows the group codes that are output if persistent reactors have been attached to an object.
ACAD_REACTORS records| Group code | Description |
102 |
"{ACAD_REACTORS" indicates the start of the AutoCAD persistent reactors group |
330 |
Soft pointer ID/handle to owner dictionary |
102 |
End of group, "}" |
The following table shows the group codes that are output if an extension dictionary has been attached to an object.
ACAD_XDICTIONARY records| Group code | Description |

Common 70 group flag bit-coded values are described in the following tables. Additional 70 group values that apply to LAYER, STYLE, and VIEW table entries are described in those tables.
Group 70 bit codes that apply to all table entries| Bit-coded value | Description |
16 |
If set, table entry is externally dependent on an xref. |
32 |
If this bit and bit 16 are both set, the externally dependent xref has been successfully resolved. |
64 |
If set, the table entry was referenced by at least one entity in the drawing the last time the drawing was edited. (This flag is for the benefit of AutoCAD commands. It can be ignored by most programs that read DXF files and need not be set by programs that write DXF files.) |
