problem with oddbpolyfacemesh
hi there,
i've got a dxf file which contains a single triangle mesh. when i come to read this file i can successfully read the mesh as an oddbpolyfacemesh, but numvertices() and numfaces() both return 0.
if i use the vertexiterator() method and type check the objects returned by the iterator then the correct number of vertices/faces are there.
i get the same results if i read the file using the odreadex example program.
thanks in advance

it seems that the file is not correct. number of vertices and faces are stored under group codes 71 and 72 in dxf polyline entity representing polyface mesh. i suppose that vertices and faces present in file but their counts are missed or incorrect.
try to use recover or call audit on loaded database.

odint16 numvertices() const;
odint16 numfaces() const;
these are defined as shorts, which means if your vert or face count
exceeds a 16 bit integer, the translation will throw and exception.
is there a fix for this?
i have many facet models that exceed 32k verts and/or 32k facets.
number of faces and number of vertices in polyface mesh are stored in dwg file as int16.....
i think this can't be solved untill autodesk guys change dwg format.
