Hello! thought i should try a smart solution, turns out to be a time hog :D a trivial problem, i need a new capsule holder for my coffeemachine, and i was tinkering around on how to achieve this.... code looks to big to be posted, so i put it up on git: https://github.com/nohkumado/openscad-nespresso i added the (hand drawing) of the polyhedron i try to achieve, the pre-render is perfectly fine, but as soon as i compile it it says: ERROR: The given mesh is not closed! Unable to convert to CGAL_Nef_Polyhedron. Geometries in cache: 4 so i am puzzled, first of all there should be only 1 geometry, and that error message is not really help full, since i don't know how to find out what's going wrong? and i would like to know how to debug something like that? if we consider the failing thing: difference() { schachtel(typ=typ, xcenter = true, wd= wd, renfort=true, h=50); color("red") translate([0,0,wd]) schachtel(typ=typ, xcenter = true, wd= 0, renfort=false); } each of the subelements compiles fine, the upper box is bigger than the diff i try to achieve, but as soon as i do the diff some spourious polygon appears in the preview at the back of the thing, and it doesn't compile anymore.... invalidating the standing fin, solves it, and i could use a cube to emulate it (as done in halter2), but that's unsatisfactory :D i would really like to know why or how this goes wrong and how to find out what is going wrong (in order to stop bothering all of you)? thanks in advance for any insight! -- ciao Bruno =========================================== http://nohkumado.eu/, <http://bboett.free.fr>http://aikido.nohkumado.eu/, <http://bboett.free.fr> http://aikido.zorn.free.fr

Have you tried View / Thrown Together mode and looked for purple faces? You should not be able to see any purple on a closed polygon. If it has a hole, or any faces are inside out, you will see purple.

My best guess is there are coincident faces in the triangle at the top when you subtract the two versions of the polyhedron.
