Object and Entity Codes
Each group code listed in this reference is presented by a numeric group code value and a description. All group codes can apply to DXF™ files, applications (AutoLISP or ObjectARX), or both. When the description of a code is different for applications and DXF files (or applies to only one or the other), the description is preceded by the following indicators:
- APP.Application-specific description.
- DXF.DXF file-specific description.
If the description is common to both DXF files and applications, no indicator is provided.
Optional codes are indicated as “optional” in the description.
