Export to STL or OBJ

Introduction
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 mm. If this is not the case you have to scale your model.

Sample part
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 [[Image:Part_Box.png|32px]]
 * Insert a cylinder by clicking on [[Image:Part_Cylinder.png|32px]]
 * Insert a cone by clicking on [[Image:Part_Cone.png|32px]]
 * Select all three objects in the tree view
 * Apply a fusion by clicking on [[Image:Part_Fuse.png|32px]]
 * Save your file

Export Method 1: Using "File > Export"

 * Switch to mesh workbench or complete workbench
 * Choose  →   →   →  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
 * Select the solid to be exported in the tree view
 * Choose  →  and set file type to "STL mesh (*.stl *.ast)"
 * Type in your file name and don't forget the extension, choose
