Introduction

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 → AddonManager.svg 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.

Current extensions

The workbenches marked with Edit Cancel.svg 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in recent versions of the software for different reasons, for example, they are obsolete, or unmaintained, or superseded by a newer workbench, or maybe they don't work with Python 3 or with Qt5, so they should be avoided.

General

Add workbenches that don't fit a special category here.

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.

Icon Name Topic Description Author Code Status
A2p workbench.svg 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 workbench icon.svg 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

Pseudo-assembly

These workbenches don't use constraints to keep relationships between parts, but simply re-position the parts in space.

Icon Name Topic Description Author Code Status
Animation Animation.png 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 workbench icon.svg 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 workbench icon.svg 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 workbench icon.svg 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
PartOMagic.svg 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 workbench icon.svg 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.

dxf_library Information and data It installs the DXF Python importer and exporter. This was required in FreeCAD versions v0.15 and below. This is not needed anymore when using the built-in DXF importer in v0.16 and above. This library is still needed if you wish to explicitly use the Python importer, or if you wish to export directly from the 3D model. Please notice that the built-in importer is faster than the Python importer, but in many cases the Python importer produces better results. yorikvanhavre https://github.com/yorikvanhavre/Draft-dxf-importer
DynamicData workbench icon.svg DynamicData Information and data It is an extension that allows creating container objects to hold custom properties of any type that FreeCAD supports, for example, length or placement.

InventorLoader workbench icon.svg InventorLoader Information and data It is an extension designed to import Autodesk Inventor files. Currently only Parts (IPT) can be displayed, not assemblies (IAM) nor drawings (IDW). As Inventor files contain a complete ACIS model representation, SAT and SAB files can also be imported.
