23/10/2015 · I check the mesh in Rhino and Rhino reports it's fine. I even tried to slice a model from Ultibots (the micro extruder body created in Alibre Design), and their STL had the same issues. Processing these files through netFabbs (Mircosoft) cloud service doesn't remove these self-intersecting surfaces. The same files slice fine in Cura and Slic3r.

[Gmsh] Some hints to solve self intersecting surface errors?

Geometry and Computation of Mesh Surfaces with Planar Hexagonal Faces. Problem Formulation We want to tile a free-form surface using planar hexagonal mesh --P-Hex mesh . Wish to have regular titling with every vertex valence = 3, (which is not possible for closed surface . if genus g ≠ 1). Approach proposed. Computing P-Hex mesh from regular triangulation of smooth surface. Introduction

Volume bounded by a triangulated surface mesh Given a closed triangulated surface mesh, each connected component splits the 3D space into two subspaces. The vertex sequence of each face of a component is seen either clockwise or counterclockwise from these two subspaces. The subspace that sees the sequence clockwise (resp. counterclockwise) is on the negative (resp. positive) side of the
