In this tutorial we will cover how to export STL/OBJ-files from FreeCAD.
Since the mesh-format STL/OBJ is dimensionless, FreeCAD will assume
on export that the units used in the model are in mm.
If this is not the case you have to scale your model .
You can use your own FreeCAD file, but you could also create a quick test file by
- Opening FreeCAD
- Create a new document
- Switch to part workbench
- Insert a cube by clicking on
- Insert a cone by clicking on
- Select all two objects in the tree view
- Apply a fusion by clicking on
- Save your file
Export Method 1: Using "File > Export"
- Switch to mesh workbench or complete workbench
- Choose Edit → Preferences → Import-Export → Mesh Formats from the top menu
- Here you can specify the maximum mesh deviation (0,1 mm is default) which controls how "fine" your mesh will get
- Close dialogue with OK
- Select the solid to be exported in the tree view
- Choose File → Export... and set file type to for example "STL mesh (*.stl *.ast)"
- Type in your file name and don't forget the extension, choose Save
Export Method 2: Using the mesh workbench in FreeCAD
- Switch to mesh workbench
- Select the solid to be meshed in the tree view
- Choose Meshes → Create Mesh from shape... from the top menu
- Select one of the three available meshers and specify the available options, for more info refer to this page (Mesh from Shape)
- Choose OK and the mesh object will be created in the tree view (with green mesh icon)
- Select the mesh object in the tree view and right click on mesh object in the tree view
- Choose Export mesh to export mesh
- You will be promted to coose file name (default is the name of the mesh object) and the file type (default is "Binary STL (*.stl)")
- Choose Save and you are finished
