Description<br />
41 View width (in DCS)<br />
11 View direction from target (in WCS)<br />
DXF: X value; APP: 3D vector<br />
21, 31 DXF: Y and Z values of view direction from target (in WCS)<br />
12 Target point (in WCS)<br />
DXF: X value; APP: 3D point<br />
22, 32 DXF: Y and Z values of target point (in WCS)<br />
42 Lens length<br />
43 Front clipping plane (offset from target point)<br />
44 Back clipping plane (offset from target point)<br />
50 Twist angle<br />
71 View mode (see VIEWMODE system variable)<br />
281 Render mode:<br />
0 = 2D Optimized (classic 2D)<br />
1 = Wireframe<br />
2 = Hidden line<br />
3 = Flat shaded<br />
4 = Gouraud shaded<br />
5 = Flat shaded with wireframe<br />
6 = Gouraud shaded with wireframe<br />
All rendering modes other than 2D Optimized engage the new 3D<br />
graphics pipeline. These values directly correspond to the SHADEMODE<br />
command and the AcDbAbstractViewTableRecord::RenderMode enum<br />
72 1 if there is a UCS associated to this view, 0 otherwise<br />
The following codes only appear if code 72 is set to 1. They define the UCS<br />
that is associated to this view. This UCS will become the current UCS whenever<br />
this view is restored (if code 72 is 0, the UCS is unchanged).<br />
