This is in addition to the requirement for DXF names for each distinct concrete class derived from ObjectARX (see Subclass Markers on page 243) |
| 102 | Control string, followed by “{arbitrary name}" or "}". Similar to the xdata 1002 group code, except that when the string begins with “{”, it can be followed by an arbitrary string whose interpretation is up to the application. The only other control string allowed is “}” as a group terminator. AutoCAD does not interpret these strings except during drawing audit operations. They are for application use |

Custom non-entity objects may use the full range, but entity classes only use 371-379 DXF group codes in their representation, because AutoCAD and AutoLISP both always assume a 370 group code is the entity's lineweight. This allows 370 to behave like other “common” entity fields |
| 380-389 | PlotStyleName type enum (AcDb::PlotStyleTypeName). Stored and moved around as a 16-bit integer. Custom non-entity objects may use the full range, but entity classes only use 381-389 DXF group codes in their representation, for the same reason as the Lineweight range above |
| 390-399 | String representing handle value of the PlotStyleName object, basically a hard pointer, but has a different range to make backward compatibility easier to deal with. Stored and moved around as an object ID (a handle in DXF files) and a special type in AutoLISP. Custom non-entity objects may use the full range, but entity classes only use 391-399 DXF group codes in their representation, for the same reason as the linewidth range above |
| 400-409 | 16-bit integers |
| 410-419 | String |
| 420-427 | 32-bit integer value. When used with True Color; a 32-bit integer representing a 24-bit color value. The high-order byte (8 bits) is 0, the low-order byte an unsigned char holding the Blue value (0-255), then the Green value, and the next-to-high order byte is the Red Value. Converting this integer value to hexadecimal yields the following bit mask: 0x00RRGGBB. For example, a true color with Red==200, Green==100 and Blue==50 is 0x00C86432, and in DXF, in decimal, 13132850 |
