Which format? I'll take it your asking about exporting STL/mesh files. In your Edit > Preferences... > Part design > Shape view tab you can change your tessellation setting. Default is 0.5000% and you can bring that down to 0.2500 - 0.1000 and you exports will be finer. You can also mesh your models in the Mesh Design Workbench which will give you more options and control over the mesh.Weeve wrote:I've noticed some of my models looks slightly choppy, specifically around seams of mirrored objects, is there an option to set the export level of detail for the triangulation, so that I can export in higher detail models?
Code: Select all
o = FreeCADGui.Selection.getSelection() bb = o.Shape.BoundBox devn = 0.03/((bb.XLength+bb.YLength+bb.ZLength)/3)*100 o.ViewObject.Deviation = devn o.ViewObject.hide() o.ViewObject.show()
I can hardly see any difference in the last three pictures. There is a slight change in the shade of grey but nothing significant in the curvature or the corners. It is probably due to image resolution, so you may better show only an enlarged detail.Mongrel_Shark wrote: ↑Mon Dec 04, 2017 2:20 amI have had cnc guys return files because what was a fine draft on an injection mold got turned into an overhang! I have had 3d printed parts not fit because of its. Its been driving me crazy for some time. Even my crappy homebrew printer (really crappy, amazed it works at all) was printing mesh artefacts everywhere! I have had tessellation settings as low as they will go for some time...
because depending on your FreeCAD version and which part of FreeCAD you are using, FreeCAD simply takes the openGL visualisation which is a mesh and uses that to create an STL which is a mesh as well. So the values in the settings quoted for PartDesign WB visualisation end up defining a simple STL mesh exported with the simple "export as STL", as distinct from using the advanced features of the Mesh workbench.
