Viewport status bit-coded flags: 1 (0x1) = Enables perspective mode 2 (0x2) = Enables front clipping 4 (0x4) = Enables back clipping 8 (0x8) = Enables UCS follow 16 (0x10) = Enables front clip not at eye 32 (0x20) = Enables UCS icon visibility 64 (0x40) = Enables UCS icon at origin 128 (0x80) = Enables fast zoom 256 (0x100) = Enables snap mode 512 (0x200) = Enables grid mode 1024 (0x400) = Enables isometric snap style 2048 (0x800) = Enables hide plot mode 4096 (0x1000) = kIsoPairTop. If set and kIsoPairRight is not set, then isopair top is enabled. If both kIsoPairTop and kIsoPairRight are set, then isopair left is enabled 8192 (0x2000) = kIsoPairRight. If set and kIsoPairTop is not set, then isopair right is enabled 16384 (0x4000) = Enables viewport zoom locking 32768 (0x8000) = Currently always enabled 65536 (0x10000) = Enables non-rectangular clipping 131072 (0x20000) = Turns the viewport off 262144 (0x40000) = Enables the display of the grid beyond the drawing limits 524288 (0x80000) = Enable adaptive grid display 1048576 (0x100000) = Enables subdivision of the grid below the set grid spacing when the grid display is adaptive 2097152 (0x200000) = Enables grid follows workplane switching |
|
340 |
Hard-pointer ID/handle to entity that serves as the viewport's clipping boundary (only present if viewport is non-rectangular) |
|
1 |
Plot style sheet name assigned to this viewport |
|
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 |
|
71 |
UCS per viewport flag: 0 = The UCS will not change when this viewport becomes active. 1 = This viewport stores its own UCS which will become the current UCS whenever the viewport is activated |
|
74 |
Display UCS icon at UCS origin flag: Controls whether UCS icon represents viewport UCS or current UCS (these will be different if UCSVP is 1 and viewport is not active). However, this field is currently being ignored and the icon always represents the viewport UCS |
|

|
112 |
UCS Y-axis DXF: X value; APP: 3D vector |
|
122, 132 |
DXF: Y and Z values of UCS Y-axis |
|
345 |

|
346 |
