Summary0001118: STL mesh size limit > 16M triangle
DescriptionWhen using .stl files in binary format, we can't use files with more than 16M triangles.

Would it be a natural limitation of file ? (16M tris is more than 800MB, but less than 2GB, limit of u_int32 index. )

Is it relevant to some standard ?

improving the limitation is quite easy, just put another number in line 20 of stlmesh.cpp :

#define MAX_STL_FILE_FACES (16*1024*1024) // 16Mb
Steps To ReproduceI would not upload my 1.4GB stl file.

The code is also limited to a 2GB file it seems. I'm not at all familiar with the STL format but judging from the code, a 2GB file should hold about 44 million triangles. So we could at least bump it up to that.
