How to convert stl to a solid mesh enabler

You can also manually close holes in your mesh object by If the normals point into the mesh the triangle will be shown in black. Tip: By choosing the mesh object in the tree view, going to the view tab in the property view and changing "Lighting" from "Two Side" to "One Side" you can identify triangles with flipped normals. Choose Meshes → Harmonize normals from the top menu.Selecting your mesh object in the tree view.Harmonizing normals of a mesh object can be done by If errors had been detected the corresponding check-boxes will be ticked and you will be able to select Repair.The texts beside the tick boxes will change to reflect results of the different tests.With the last point in the list reading "All above tests together" click on Analyze.Make sure the pull down menu on the top right corner displays the name of your mesh object.Choose Meshes → Analyze → Evaluate & Repair mesh.Make sure that your mesh object is selected in the tree view.Open FreeCAD and the sample FreeCAD file containing the mesh object.In this tutorial we will use the mesh workbench within FreeCAD to clean/repair/verify the mesh of our sample file. Meshlab (Windows/Linux/Mac) - Open Source.Netfabb Basic (Windows/Linux/Mac) - free for personal use (automatic mesh repair available).

Some users like to use third-party software for cleaning and repairing meshes, for example FreeCAD has some capabilities for mesh operation in mesh workbench and OpenSCAD workbench (some operations need OpenSCAD to be installed and configured in the FreeCAD-preferences). For a successful conversion from mesh to solid we need to make sure that the mesh is “water-tight” (has no holes) or doesn’t have any other errors.įreeCAD’s aim is not to be a good mesh modeler, it is designed to be a solid modeler. But our goal is to have a solid which can be measured and changed (adding pads/pockets.

Save your file with File → Save to get a FreeCAD-File containing a mesh objectįor importing a STL or OBJ file into FreeCAD, create a new FreeCAD document und choose File → Import from the top menu.Ĭleaning and repairing the STL/OBJ-File for preparing importīasically, FreeCAD would import any STL/OBJ-File.

Insert a torus by clicking on Meshes → Regular solid., choosing settings like:.

If this is not the case you have to scale your model either in the application it was created with (before exporting it) or you have to scale your model in FreeCAD after import and conversion to a solid.įor this tutorial you can use your own STL file or create a demo file by doing this: Since the mesh-format STL/OBJ is dimensionless, FreeCAD will assume on import that the units used in the model are mm. In this tutorial we will cover how to import STL/OBJ files in FreeCAD.

3 Cleaning and repairing the STL/OBJ-File for preparing import.
