Common Group Codes for Entities
The following
table shows group codes that apply to virtually all graphical objects.
Some of the group codes shown here are included with an entity definition
only if the entity has nondefault values for the property. When
you refer to the group codes by entity type, the lists of codes
associated with specific entities, keep in mind
that the codes shown here are also present.
NoteDo not write programs
that rely on the order shown in these DXF code tables. Although
these tables show the order of group codes as they usually appear,
the order can change under certain conditions or may be changed
in a future AutoCAD® release. The code that
controls an entity should be driven by a case (switch) or a table
so that it can process each group correctly even if the order is
unexpected.
When a group is omitted, its default value upon
input (when using OPEN) 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 SAVEAS). For information about abbreviations
and formatting used in this table, see Formatting Conventions in This
Reference.
