The following group codes apply to VPORT symbol table entries. The VPORT table is unique: it may contain several entries with the same name (indicating a multiple-viewport configuration). The entries corresponding to the active viewport configuration all have the name *ACTIVE. The first such entry describes the current viewport. In addition to the group codes described here, see Common Group Codes for Symbol Table Entries. For information about abbreviations and formatting used in this table, see Formatting Conventions in This Reference.

Standard flag values (bit-coded values): 16 = If set, table entry is externally dependent on an xref 32 = If both this bit and bit 16 are 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 does not need to be set by programs that write DXF files) |
