93 |
* Vertex flags (70) group has the 128 bit set but not the 64 bit. The 10, 20,
|
94 |

|
95 |
* written as zero in a DXF file.
|
96 |
*
|
97 |
* The vertex indexes that define the mesh are given by 71, 72, 73, and 74
|
98 |
* groups, the values of which are integers specifying one of the previously
|
99 |
* defined vertices by index.

100 |
*
|
101 |
* If the index is negative, the edge that begins with that vertex is invisible.

103 |
* The first zero vertex marks the end of the vertices of the face.

104 |

106 |
* zero, they are present in DXF only if nonzero."
