FreeCAD, like many modern design applications such as Revit or CATIA, is based on the concept of Workbench. A workbench can be considered as a set of tools specially grouped for a certain task. In a traditional furniture workshop, you would have a work table for the person who works with wood, another one for the one who works with metal pieces, and maybe a third one for the guy who mounts all the pieces together.
In FreeCAD, the same concept applies. Tools are grouped into workbenches according to the tasks they are related to.
Currently we have the following workbenches available:
- The Part Design Workbench for building Part shapes from sketches
- The Draft Workbench for doing basic 2D CAD drafting
- The Mesh Workbench for working with triangulated meshes
- The Part Workbench for working with CAD parts
- The Image Workbench for working with bitmap images
- The Raytracing Workbench for working with ray-tracing (rendering)
- The Drawing workbench for displaying your 3D work on a 2D sheet
- The Robot Workbench for studying robot movements
- The Sketcher Workbench for working with geometry-constrained sketches
- The Arch Workbench for working with architectural elements
- The OpenSCAD Workbench for interoperability with OpenSCAD and repairing CSG model history
- The Assembly Workbench for working with multiple shapes, multiple documents, multiple files, multiple relationships...
- The Fem Workbench for Pre- and Post-processing FEM studies
- The Workbench Ship FreeCAD-Ship works over Ship entities, that must be created on top of provided geometry.
- The Plot Module The Plot module allows to edit and save output plots created from other modules and tools.
New workbenches are in development, stay tuned!
When you switch from one workbench to another, the tools available on the interface change. Toolbars, command bars and eventually other parts of the interface switch to the new workbench, but the contents of your scene doesn't change. You could, for example, start drawing 2D shapes with the Draft Workbench, then work further on them with the Part Workbench.
