If OpenSCAD file is available - it can be processed in OpenSCAD command line to make it smooth upon import to FreeCAD.

MeshLab has export to DXF 3D format, and importing to FreeCAD works (MJ).

You have to repair mesh, convert mesh to shape, and convert to solid (meshes are shells). FreeCAD has an export of STL to STEP, but sometimes it doesn't work.Seems limit will be length of a file that FreeCAD can handle if done this way.Here is an STL to OpenSCAD converter on thingiverse, which converts STL format to OpenSCAD format.

Reverse Engineering STL to OpenSCAD so it Can Be Edited in FreeCAD PITA, but that's all we have for now in the open source.Ī good open source STL to STEP converted would be very useful to the open source community.ĭoes the OpenSCAD workbench do the same in FreeCAD? Yes, as long the OpenSCAD text file is available, it can be rendered - and EDITED - in the FreeCAD OpenSCAD workbench - apparently as if it were a solid object - see. Modification occurs in the STL editor, and then the file is imported to FreeCAD. It appears that the best workflow for STL modification (derivatives of STL files when FreeCAD source is not available) is to use an STL editor such as OpenSCAD or BlocksCAD or OpenJSCAD. Only on screen in openscad some faces seemed to be. Sometimes STLs can be imported and made into solids in FreeCAD, see FreeCAD 101 video number 2. i got the correct result (with other, more complex stl too) and i could export them to valid stl-files. FreeCAD works easily with STEP imports - and STEP files can be modified. However, one has to step into the slow lane by using OpenSCAD to modify STLs, as there is no great way to edit STLs in FreeCAD.Įffectively, STLs are useless from the standpoint of re-design within FreeCAD -as they are meshes and do not work the same way as solids (boundary representation objects like STEP). STL files are to be found everywhere in the 3D printing world, and it is useful to edit them. 2 Reverse Engineering STL to OpenSCAD so it Can Be Edited in FreeCAD.
