Linear_extrude(height=totalHei, center=false, convexity=10) > This is the minimal code I have used for the example: Opening the single pieces in meshlab did not show any error in the mesh aswell. The mesh itself is generated by openscad itself from two imported svg files, so they should be allright. I have rendered the single pieces into an stl file which worked flawlessly but when I tried to difference the two stl-files I have run into the same problem again. * It should be generated a puzzle piece shaped bowl, but instead a closed shape puzzle piece was generated as if the difference function would have no effect. (see "rendered.png").ĮRROR: The given mesh is not closed! Unable to convert to CGAL_Nef_Polyhedron.

If you press the "Render" button (F6) only a closed shape of the outer puzzle piece will be rendered without the cutout.

You will get a preview image that looks allright: see "awaited.png" I started with point/face data for the regular polyhedra which I found in William Adam’s work and added OpenSCAD code to create cylinders along each side of each face. I wondered if I could do wire-frame models in OpenSCAD.

Open the provided file "JFAS-Logo_Bug.scad" in openscad. Laura Taalman is on a roll with her complex polyhedra, producing some wonderful structures.

Download and uncompress the example zip file here.I wanted to render a kind of puzzle shaped bowl, that is construced by cutting out an inner puzzle piece of an outer puzzle piece in the same shape (see awaited.png and cutout.png in the download link).I found a mention of an approach developed by George. > Openscad Version: OpenSCAD-2021.01-x86_64.AppImage I wondered if a more general approach to mapping between polyhedral graphs and 3D polyhedron was possible.
