Here is how to do it utilizing a pair of important constructive and free programs side by side Sketchup MeshLab and Accutrans3D . Luckily all it took was using Close Holes in MeshLab to close up the model and make it suitable for printing. I have installed the Cura Plugin Extension Mesh Tools and it is successfully fixing the normals and most of the holes . It must be the correct dimensions. After cleaning I reduced the number of faces from about 160000 to just 4500 using one of the many filters in Meshlab called Quadric Edge Collapse Decimation. stl . However by trying nbsp 9 Nov 2016 are parts of the model where the dots have not been connected to create a solid. when I check afterwards So I am guessing this might be a caching problem because the mesh is always identical after fill_holes as MeshLab is an open source advanced 3D mesh processing software system. In wireframe good ol 39 Santa now looks like this Jul 03 2011 While opening MeshLab asks whether it is all right to unify duplicate vertices and one can select OK. It seems desirable to close the shell before decimating though. If the surface mesh is not watertight or in other words if it contains any holes it does not properly represent the 3D geometry of interest. After import the model is for FreeCAD just an assembly of faces. Here is a link http meshlab. However this amount of post processing has a couple of drawbacks. Both of these closed surfaces gave comparable volumes from MeshLab. If you have to mesh a lot of different designs I would prefer the generation of the STL using snappyHexMesh. Make a copy of your basic color layer. For Remeshing and creating the surface I wanted to use Poisson Surface Reconstruction. This property is usually referred to as a being watertight.
