Clipping boundary type. 1 = rectangular, 2 = polygonal

91

Number of clip boundary vertices that follow

14

Clip boundary vertex (in OCS). DXF: X value; APP: 2D point (multiple entries)
Notes:
1) For rectangular clip boundary type, two opposite corners must be specified. Default is (-0.5,-0.5), (size.x-0.5, size.y-0.5).
2) For polygonal clip boundary type, three or more vertices must be specified. Polygonal vertices must be listed sequentially.
