* Vertex flags (70) group has the 128 bit set but not the 64 bit. The 10, 20,
|
101 |

|
102 |
* written as zero in a DXF file.
|
103 |
*
|
104 |
* The vertex indexes that define the mesh are given by 71, 72, 73, and 74
|
105 |
* groups, the values of which are integers specifying one of the previously
|
106 |
* defined vertices by index.
|
107 |
*
|
108 |
* If the index is negative, the edge that begins with that vertex is invisible.

109 |
*
|
110 |
* The first zero vertex marks the end of the vertices of the face.
|
111 |

|
113 |
* zero, they are present in DXF only if nonzero."
