msasu，
我不确定这是否是您需要的，但我在AutoCAD Developer帮助的DXF参考/表格部分找到了它。
查看
- 100 Subclass marker (AcDbViewTableRecord)
- 2 Name of view
- 70 Standard flag values (bit-coded values):
- 1 = If set, this is a paper space view
- 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 need not be set by programs that write DXF files)
- 40 View height (in DCS)
- 10 View center point (in DCS)
- DXF: X value; APP: 2D point
- 20 DXF: Y value of view center point (in DCS)
- 41 View width (in DCS)
- 11 View direction from target (in WCS)
- DXF: X value; APP: 3D vector
- 21, 31 DXF: Y and Z values of view direction from target (in WCS)
- 12 Target point (in WCS)
- DXF: X value; APP: 3D point
- 22, 32 DXF: Y and Z values of target point (in WCS)
- 42 Lens length
- [color=red]43 Front clipping plane (offset from target point) [/color]
- [color=red]44 Back clipping plane (offset from target point) [/color]
- 50 Twist angle
- 71 View mode (see VIEWMODE system variable)
- 281 Render mode:
- 0 = 2D Optimized (classic 2D)
- 1 = Wireframe
- 2 = Hidden line
- 3 = Flat shaded
- 4 = Gouraud shaded
- 5 = Flat shaded with wireframe
- 6 = Gouraud shaded with wireframe
- All rendering modes other than 2D Optimized engage the new 3D graphics pipeline. These values directly correspond to the SHADEMODE command and the AcDbAbstractViewTableRecord::RenderMode enum
- 72 1 if there is a UCS associated to this view, 0 otherwise
