I am using STL export, and also meshing capabilities. An in both cases it produces a lot of wrong triangles (I am using an external tool to check this).
Note that the problem arise even with simple geometry : for instance STL export failed to correctly export an hollow semi-sphere. In this case, it produces a *lot* of small weird triangles at one pole, while the rest of the shape seems good tesselated in the STL file.
Is there a way to get good stl export ?
