01:07.57 nmz787 got a seg-fault bug here with 3dm-g.... used the pointcloud library (pcl) .pcd to nurbs approximation example on the bunny point cloud... then just tried throwing that .3dm at 3dm-g and it dies, seemingly differently on the compiled (recent SVN from a few weeks ago) http://paste.pound-python.org/show/SDnebWuTd0eZJINMilY5/ versus the ubuntu .deb install http://paste.pound-python.org/show/Y3DhMbATIFuTkXXxo58T/
01:10.08 nmz787 here is the pointcloud to 3dm example walkthrough... basically though I just git cloned their github, compiled with examples, then ran the example binary on the bunny.pcd they had as a test... took a few seconds to get a decent one-sided surface, but i went to sleep after a few minutes and it was still cranking away. Had a nice 3d view of the surface in the morning and a 3dm file, and a message saying it had finished. ...

19:07.08 ejno nmz787: the crash should be fixed in SVN now, although one of the two objects (the ON_NurbsCurve) isn't able to be imported by 3dm-g yet
19:10.22 ejno can't work on it now, but I will try to add support for those objects when I have some time

23:36.10 nmz787 ejno: i'm not sure what you mean exactly... the crash will be fixed, but since something isn't supported, it will not be able to complete the conversion (but erroring out gracefully instead of crashing)?
