FreeCAD enables you to create a parametric 3D design, which makes it particularly efficient for mechanical or engineering designs. It is fairly easy to learn, so you could even use it if you never used CAD software before. Being Open-Source also makes it particularly customizable. For example, you can add new functionalities or automate processes directly by writing scripts.


HeeksCAD is a good way for people who are new to 3D design to learn how to handle this kind of CAD software. It offers all the common functions you would need to make basic (yet good) 3D models. 

Just like FreeCAD, you can use parametric designs to create and modify your objects. You may encounter difficulties if you try to realize complex models (a lot of the usual tools are not available yet), but again this is not the main goal of HeeksCAD.


OpenSCAD is CAD software that enables you to work on solids in two different modes. Indeed, you can either use constructive solid geometry, where you define your design as a result of primary operations (such as sums or subtractions) or use a classic extrusion technique, where you make 2D designs that you then turn into 3D. Either way, the software is fitted to export an STL file and has a good community behind it to support you whenever you have issues.


This open-source and free CAD software is perfect for beginners, as it is specifically designed as Linux CAD Software and offers general tools. However, LibreCAD just works in two dimensions.
