I can not reproduce the crash. It exports an STL fine for me with 211ae8c
What is your "export chord tolerance" ?

Sorry, something went wrong.

Yeah it sounds like a duplicate of #320

Ahh yes - with 0.01 chord tolerance and 200 segments:

Unhandled exception at 0x77289A09 (ntdll.dll) in solvespace.exe:
0xC00000FD: Stack overflow (parameters: 0x00000001, 0x00E02FFC).

So it is a stack overflow, and by the look of it exactly in bsp.cpp as in #320
