One of the key things to know about FreeCAD is that, as an open-source project, it is completely free for all to use. It’s primarily aimed at those working in mechanical engineering and product design, and with its scriptable CAD, there are options for electrical or architectural design too.įreeCAD was released in October 2002 by authors Jürgen Riegel, Werner Mayer, and Yorik van Havre who wanted to create open-source CAD software to work on all platforms. What is FreeCAD?įreeCAD is a 3D modeler used mostly for designing real-life objects of any size. So let’s get into the details and find out more about FreeCAD and Fusion 360. These are both extremely high functioning software that can be used for complex designs, and many of the features are likely to be used only by those with a background in engineering, however, there is plenty to attract a hobby user, learner, or small business user too. FreeCAD allows you to maintain control of your files, whereas Fusion 360’s files are stored in the cloud.FreeCAD is free to extend, whereas Fusion 360’s extensions and plugins are of an additional cost.FreeCAD is still in development, whereas Fusion 360 is a complete product.FreeCAD has a steeper learning curve, whereas Fusion 360 is relatively user-friendly and intuitive.FreeCAD is open source and therefore will always be completely free, whereas Fusion 360 has free licenses only for educators and students.The main differences between FreeCAD and Fusion 360 are: Main Differences Between FreeCAD vs Fusion 360 Fusion 360: Which One Is Better for 3D Printing? The Alternatives to FreeCAD and Fusion 360.Main Differences Between FreeCAD vs Fusion 360. One must force a change in the underlying model to cause the tessellation to be recomputed - for example, by editing a sketch parameter (Setting it to its original value will suffice). In addition, exporting immediately after changing the display tessellation preference value will not have the desired effect because display tessellation is not updated immediately. However, because those parameters control the tessellation used to render shapes on the display, decreasing them will slow down display rendering, often significantly. When exporting from another workbench using File → Export., the tessellation is controlled by the overall display tessellation set in Edit → Preferences. In such cases you may need a finer tessellation value. If you are exporting to use in 3D-printing, this may result in an under-sized hole, for example. This results in slightly under-sized inside dimensions for curved surfaces. Curved surfaces are represented in STL as a series of straight-line segments, generated via tessellation.For example, you can fuse meshes before exporting. When you have more than one Body to convert you can use Tools from Mesh Workbench.The default file type is "Binary STL (*.stl)".If you include an extension which matches the file type, no additional extension will be added. If you include an extension which does not match the selected file type, an extension for the selected type will be added when the file is saved. The extension will be set based on the file type. Fill in the file name the extension is not necessary.Right click the mesh object in the tree view and choose Export mesh.The mesh object will be created in the tree view (with green mesh icon ). For more information refer to Mesh from Shape. Select one of the available meshers and specify the available options.Choose Meshes → Create Mesh from shape.Select the solid to be meshed in the tree view.Choose Save.Įxport Method 2: Using the Mesh Workbench in FreeCAD You must include the extension ".ast" in the file name to produce a. and set file type to "STL mesh (*.stl *.ast)". Select the solid to be exported in the tree view.Apply a fusion by clicking on Part Fuse.Insert a cube by clicking on Part Box/Cube.You can use your own FreeCAD file, but you could also create a quick test file by If this is not the case you have to scale your model. The mesh-format STL/OBJ is dimensionless FreeCAD will assume on export that the units used in the model are in mm. In this tutorial we will cover how to export STL/OBJ-files from FreeCAD. 4 Export Method 2: Using the Mesh Workbench in FreeCAD.3 Export Method 1: Using "File → Export".
