| Summary | 0002002: Mesh Faces Not Conforming With Tessellation Settings | ||||
| Description | When exporting mesh, (.stl) or rendering with POV-Ray, mesh faces are not adhering to the setting defined in the tessellation max deviation setting. | ||||
| Steps To Reproduce | Create a Sphere in the Part Workbench. Export Sphere as mesh with default tessellation setting - 0.5 Export Sphere as mesh with new tessellation setting - 0.01 Faces of exported mesh are the same. | ||||

In Mesh module's exporter() method (defined in src/Mod/Mesh/App/AppMeshPy.cpp ) , there's a line: float fTolerance = 0.1f; I suspect that's the problem - it ends up getting passed on to OCC/OCE for exporting regular parts. My inclination (haven't thought about this too much) is to add a preferences page for the mesh module, any thoughts? |

the tessellation max deviation is a visual setting, I think it should not be used for mesh conversion (it could easily lead to huge conversions that could block the whole thing). I think Ian's suggestion is good. Ideally all the meshing options of the Mesh WB should be made available. I did something like that for the DAE format (enable arch WB and look in preferences). This could actually be used for all implicit Part to Mesh conversions... |

I've started working on adding a tab for "Mesh Formats" under the "Import-Export" preferences section to address this. Edit: Pull request https://github.com/FreeCAD/FreeCAD/pull/78 |
