VIEW (DXF)

The following group codes apply to VIEW symbol table entries.

VIEW group codes
Group code	Description
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 does not need to 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
43	Front clipping plane (offset from target point)
44	Back clipping plane (offset from target point)
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
73	1 if the camera is plottable
332	Soft-pointer ID/handle to background object (optional)
334	Soft-pointer ID/handle to live section object (optional)
348	Hard-pointer ID/handle to visual style object (optional)
361	Sun hard ownership ID

The following codes appear only if code 72 is set to 1. They define the UCS that is associated to this view. This UCS will become the current UCS whenever this view is restored (if code 72 is 0, the UCS is unchanged).

VIEW with UCS group codes
Group code	Description
110	UCS origin (appears only if code 72 is set to 1) DXF: X value; APP: 3D point
120, 130	DXF: Y and Z values of UCS origin
111	UCS X-axis (appears only if code 72 is set to 1) DXF: X value; APP: 3D vector
121, 131	DXF: Y and Z values of UCS X-axis
112	UCS Y-axis (appears only if code 72 is set to 1) DXF: X value; APP: 3D vector
122, 132	DXF: Y and Z values of UCS Y-axis
79	Orthographic type of UCS (appears only if code 72 is set to 1): 0 = UCS is not orthographic 1 = Top; 2 = Bottom 3 = Front; 4 = Back 5 = Left; 6 = Right
146	UCS elevation (appears only if code 72 is set to 1)
345	ID/handle of AcDbUCSTableRecord if UCS is a named UCS. If not present, then UCS is unnamed (appears only if code 72 is set to 1)
346	ID/handle of AcDbUCSTableRecord of base UCS if UCS is orthographic (79 code is non-zero). If not present and 79 code is non-zero, then base UCS is taken to be WORLD (appears only if code 72 is set to 1)
