Enumeration AcDbDxfCodeConst

DXF group codes used by AutoCAD for reading and writing DXF/DWG data.

This enum mirrors Autodesk.AutoCAD.DatabaseServices.DxfCode exactly. Values indicate both semantic meaning and expected data type.

Remarks

  • Group codes 0–9: string / symbol data
  • Group codes 10–59: floating-point values
  • Group codes 60–79: short integers
  • Group codes 90–99: 32-bit integers
  • Group codes 100–107: subclass / control strings
  • Group codes 300–369: strings / handles
  • Group codes 370–389: lineweight / plot style
  • Group codes 400+ : extended data (XData)
  • Negative values : internal / structural markers
