Workbenches are common to most 3D CAD packages. The photo below shows the typical workbenches that are available on FreeCAD. The Sketcher, Part and Part Design are standard workbenches on FreeCAD but are also common to other 3D CAD packages such as CATIA. The Sketcher, Part and Part Design workbenches are what I will be using the most of intially as they are the ones that are primarily used to build your 3D CAD parts. An assembly workbench is another I will use. FreeCAD does not have a standard assembly workbench hence it is an add on. There are lots of add on workbenches developed by 3rd parties apart from the assembly workbenches there are ones available for Openfoam CFD, aircraft design, boat design, etc. I am hoping to create an add on workbench for RC helicopters using python marcos I have created building my RC helicopter parts. Strangely FreeeCAD has standard FEM workbench which can be used to do stress analysis on your CAD parts, its something I might look into in the future as I become more experenced using FreeCAD.
Panels on the FreeCAD start page
Monday 16 February 2026
The FreeCAD start page generally has a number of panels. You can select which ones are visible from 'Panels' in the 'View' menu. There are four panels on the version of FreeCAD that I am currently using. The 'Selection' panel allows you to see what attributes are selected. The 'Report' view allows you see any errors, etc that have happened with operations that you are doing. The 'Combo' view is important its gives a lot of information on your model attributes, etc. The 'Python Console' is one I think is the most powerful one as everytime an operation is executeded in FreeCAD it generates a bit of python code. You can and I will be using this code to create marcos which will allow CAD models to be generated automatically from a series of design parameters, I hope to demonstrate this with a simple example in the next post.

Over the coming weeks and months I hope to build a CAD model of a RC Helicopter using FreeCAD. FreeCAD as the names suggests is a free or opensource CAD software package it can be download from the official website, https://www.freecad.org/downloads.php?lang=en for the three main operating systems: Windows, Apple and Linux. I will be using the Windows version, my version of FreeCAD is slightly earlier version 0.2 whereas FreeCAD is up to version 1.0 at the time of writing. I've also introduced FreeCAD in more detail previously on a website blog, www.eiteog.com/EiteogBLOG/No60EiteogBlogFreeCAD.html .
