External workbenches are those created by power users which haven't been integrated into the main FreeCAD source code.
Most of these workbenches can be installed from the Addon Manager (menu Tools → Addon manager). For manual installation see Installing more workbenches. If there are specific instructions or prerequisites for using these workbenches, these should be noted in each workbench's home page.
These workbenches aren't supported by the main FreeCAD development team, so they aren't tested to work with every version of FreeCAD. Questions, bug reports, and improvement requests should be made directly to the authors of the particular workbench.
The lists in this page are organized in topics, but not all of them are available in the Addon Manager. See external workbench list for an alphabetic list of those workbenches that really appear in the Addon Manager.
The workbenches marked with are not recommended in recent versions of the software for different reasons, for example, they are obsolete, or unmaintained, or superseded by a newer workbench, or maybe they don't work with Python 3 or with Qt5, so they should be avoided.
Add workbenches that don't fit a special category here.
|MOOC||Education||It provides an interactive tutorial to learn about FreeCAD directly inside the program. It allows you to evaluate your self-learning.||rockn||https://framagit.org/freecad-france/mooc-workbench|

Assembly and animation
As of FreeCAD 0.19 there is no official assembly workbench. However, several external tools have been created or are in development to manipulate objects to produce assemblies.
Note: assembly workbenches are generally incompatible with each other. If you create an assembly with one of these workbenches, you should stick to the original workbench, and not use another assembly workbench in the same document.
|A2plus||Assembly||It provides tools to create multi-part assemblies. It is a fork and extension of the older Assembly2 Workbench, but it is not compatible with it.||kbwbe||https://github.com/kbwbe/A2plus|
|Assembly3||Assembly||It is used to perform assembly of different bodies contained in a single file or in multiple documents. It was a testbed for the App Link object that was eventually included in the master code. It is the most complex solution and supports things like interactive kinematics.||realthunder||https://github.com/realthunder/FreeCAD_assembly3|
|Assembly4||Assembly||It is a solution based on the enhanced expression engine and the App Link object developed in the branch of Assembly3. Assembly4 does not work with a proper constraint solver, instead it uses the expression engine to position bodies with respect to Local Coordinate Systems (LCS).||Zolko||https://github.com/Zolko-123/FreeCAD_Assembly4|
These workbenches don't use constraints to keep relationships between parts, but simply re-position the parts in space.
|Animation||Pseudo-assembly||It contains many tools to simulate movement of parts, create sequences of pictures, and thus produce an animation. The position and rotation of objects can be changed at different times, but also other properties like visibility, transparency, shape color, and camera position.||microelly2||https://github.com/microelly2/Animation|
|ExplodedAssembly||Pseudo-assembly||It allows creating exploded views and animations of assemblies. It was previously known as "ExplodedAnimation".||JMG1||https://github.com/JMG1/ExplodedAssembly|
|Lattice2||Pseudo-assembly||It provides tools for working with placements and arrays of placements. It is a sort of assembly workbench but there are no constraints nor relationships. Instead, the workbench focuses in arrays of placements that can be generated, combined, transformed, superimposed, and populated with shapes. It can also create exploded assemblies.||DeepSOIC||https://github.com/DeepSOIC/Lattice2|
|Manipulator||Pseudo-assembly||It is aimed at helping users in aligning, moving, rotating, and measuring 3D objects through a friendly graphical interface.||easyw||https://github.com/easyw/Manipulator|
|Part-o-magic||Pseudo-assembly||It is an experimental workbench that provides some improvements to Std Part and PartDesign Body containers (automatic grouping, visibility automation, etc.), in order to work with documents that have multiple parts with deep feature hierarchies. It provides a Body-like container for the Part Workbench, and for other workbenches that produce solid shapes. Part-o-magic does not provide assembly constraints, but the tools included may be useful in conjunction with a true assembly workbench.||DeepSOIC||https://github.com/DeepSOIC/Part-o-magic|
|Workfeature||Pseudo-assembly||It provides tools to produce different points, axes, and planes, in order to facilitate the creation of assemblies. This workbench is based on the older Workfeatures macro, which was hosted in the macros recipes page. Currently, the macro has a bit more functionality than the workbench, but eventually the workbench will integrate all existing tools of the macro. They also differ in the graphical user interface; the macro creates a panel next to the tree view and the task panel, while the workbench provides its tools in toolbars, just like other workbenches.||Rentlau||https://github.com/Rentlau/WorkFeature-WB|
|Autoload||Customization||It is a small extension that allows you to select the workbenches that should be loaded when you start FreeCAD. It can be used in combination with other extensions from the same author such as CommandPanel, PieMenu, and ShortCuts.||triplus||https://github.com/triplus/Autoload|
|CommandPanel||Customization||It is an extension that provides a panel that can be used store tools from different workbenches.||triplus||https://github.com/triplus/CommandPanel|
|Glass||Customization||It is an extension that shows the combo view (tree view and property editor) as a transparent overlay over the 3D view.||triplus||https://github.com/triplus/Glass|
|IconThemes||Customization||It is an extension that provides the ability of changing the icons of the default program. Icon sets aren't provided with this extension; these need to be provided separately.||triplus||https://github.com/triplus/IconThemes|
|Launcher||Customization||It is a small extension that provides a dedicated dialog box to search and launch commands. Instead of clicking on a toolbar button or menu entry, this method of executing commands may be faster for some users.||triplus||https://github.com/triplus/Launcher|
|PieMenu||Customization||It is a small extension that shows a pie menu to select tools or commands when thekey is pressed. A pie menu is an interface that appears in Blender and other systems like Android mobile phones to launch commands.||triplus||https://github.com/triplus/PieMenu|
|SelectorToolbar||Customization||It is a small extension that provides a point and click experience for switching workbenches.||triplus||https://github.com/triplus/SelectorToolbar|
|ShortCuts||Customization||It is a small extension that provides a manager and overlay for shortcuts.||triplus||https://github.com/triplus/ShortCuts|
