if( vertexpts.first() != vertexpts.last() )

//and it crashes hard here:

i'm using the 1.14 libraries, where am i going wrong?
i've upgraded to the 2.2 libraries, and the problem still exists. am i the only one unable to create a hatch using this method? my next course of action is to convert my polygon points to edge pointers. any advice is appreciated.

you need specify polyline flag in looptype parameter:
code:
phatch->appendloop(oddbhatch::kexternal | oddbhatch::kpolyline, vertexpts, vertexbulges);

thank you,
that solved the issue.
