Hi Kelly,

It depends on the kind of problems the mesh has.  Seg3D, and most other isosurfacing software, use a marching cubes algorithm, which doesn’t guarantee any element quality of the resulting mesh.  I suspect this is what you are seeing, as the algorithm will generate acceptable elements for the most part, but sometimes not. If you are seeing other problems, such as overlapping elements or mesh errors.  
SCIRun and MeshLab have tools to analyze mesh quality and fix them.

Subject: Export of STLS - Coronary Arteries

Message: Hi there,
I've been making really great anomalous coronary artery models. They look great in all of my post-processing software - meshlab, meshmixer, etc. I have about 40 models total. I've decided to use Netfabb to take some measurements and remesh them (later to be used for computational fluid modeling). Some of the models load in perfectly and others are flagged for mesh quality issues. Is there any reason why some STLs would be flagged and some wouldn't? I isosurfaced and exported them all the same way in Seg3D?
