DXF Group Codes
OBJECTS Section
Common Object Group Codes

The following table shows group codes that apply to virtually all non-graphical entities (objects). 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. Some of the group codes are included with an entity only if the entity has non-default values for these properties. When a group is omitted, its default value upon input (when using DXFIN) is indicated in the third column. If the value of a group code is equal to the default, it is omitted upon output (when using DXFOUT).
