The result of my FreeCAD constructions is always the 3D printed. Also the many useful posts in this forum.Īnd when I'm fit with FreeCAD, I hope to also make my contribution. For starting into FreeCAD your YouTube movies have helped me really. But the easier way I think is using the standard settings.īy the way Mark.

For this reason I made the detour with Gmesh. After a long construction time I start FreeCAD new, and the problem is mostly resolved. With the default setting I had often holes especially when rounding. I have tested the variant Mefisto and Netgen in FreeCAD also. Many thanks for the detailed description. You have additional options there which can produce equivalent meshes as gmsh ( as both can use netgen ) In general freecad sometimes produce rather curious meshes, so if you choose a high allowed deviation the triangles which can be seen may look strange.Īlso note that you can use different mesh creation methods from freecads mesh workbench, see menu->create mesh from shape. So in theory it should be without difference for you which mesh you use if the deviation parameter is set to the same value. and for this gmsh and freecad provide an identical measure: the maximal allowed deviation. all you care about in 3d printing is how non-flat surfaces and curfes are aproximated. There it is enough to triangulate a plane with two triangles, it gives you no loss in precission.

However, this is unneeded for 3d printing. This is realy good for fem as you want a uniform mesh to ease the solution and get a good quality approximation over the whole part. Gmsh is intended to be a fem preprocessor and this you can see in the mesh: It creates meshes with a rather uniform triangulation with a higher density at critical (round) parts.
