In addition, the program allows the creation and modeling of relatively large models, which require a lot of parts. A design mode which makes the program more accessible to children, and which makes LeoCAD one of the main software used for educational purposes. Targeted towards beginners and people wishing to discover 3D modeling, this free CAD software allows you to design models using LEGO bricks. If you are a LEGO enthusiast, then LeoCAD software is the CAD program for you. Subsequently, if you want to design more technical and complex models, you will have to change the platform and go to OpenSCAD, a platform which is considered to be the advanced version of BlocksCAD.

You are then left with the simple task of exporting the file in STL format in order to be able to 3D print it.

The platform functions somewhat similarly to LEGO, in that you must add take away building blocks of various shapes to obtain the final part. Easier to use than OpenSCad, it recommended to begin with BlocksCAD.

This free CAD software was primarily designed for beginners and the education sector. Note that there are also free CAD software for certain profiles ( Fusion 360 for individuals, CATIA for students) but we have deliberately left them aside. We have therefore divided our selection into two, the 100% free software and those with premium options. However, a few offer a premium version, meaning some features will be free but if you want to go further, you will have to pay a subscription. As you will have understood, each CAD software has its specificities and will meet the needs of beginners or more experts. So, faced with the multiplicity of tools available on the market today, how do you choose? We’ve put together a selection of free CAD software which will allow you to test different options without costing you a dime. Most of these software also offer functionalities for modifying a 3D model, visualization and even simulation before printing. They allow you to imagine any shape, whether you start from scratch or an existing model. This stage of conception is essential and can be completed using several tools, notably CAD (computer-aided design) software. Before you can 3D print a part, you have to create a model.
