FreeCAD

When it comes to 3D design, working with the proper tools is mandatory. While there are professional applications out there, free alternatives also have a lot to offer. One such utility is FreeCAD, a CAD application built in Qt and Python and released under an open-source license.

FreeCAD focuses on procedural geometry and parametric modeling to provide a comprehensive toolbox for designing real-life objects. It allows you to sketch both 2D and 3D components, storing a model’s history to help you quickly make modifications to its parameters. 2D objects you create in FreeCAD can be used to generate other components, meaning you can turn a bidimensional model into a 3D one and viceversa.

There is a plethora of file formats compatible with FreeCAD, which makes it quite versatile. It can read 3ds studio meshes, DXF, BRP, DAT, SVG, MED, IGES, BMP, JPG, IFC, OCA, ASC, SVG, WRL, and others, making it compatible with other 3D modeling tools that you might use alongside FreeCAD.   But it’s not just the range of supported formats that makes It worth your while. Due to its viewing options, design and drawing tools, inspection tools and technical drawing capabilities, FreeCAD can be used to create models for various domains, including mechanics and engineering, architecture, or product design.

The application comes packed with functions that allow creating and manipulating 3D objects. The toolbar comprises shortcuts and frequently used controls for changing the view to make sure you pay attention to the smallest detail of your design. It features orthographic, axonometric and perspective views, also allowing you to create custom views.

For your convenience, you can change the camera position and toggle stereo mode. Zooming options are also available. You can also move, rotate, scale or edit objects in your design.

The integrated parameter editor allows you to check out the parameter list of your model and edit their values. The editor, along with the scene inspector, the distance measurement tool and the unit calculator, provide assistance in creating compelling models. You can use them to create complex components, design meshes and set up simulation environments with a robot and various objects. To automate frequent operations, FreeCAD features macro recording and an integrated debugger.

There is a lot more to discover in FreeCAD, which can only be done by taking it for a spin. It is, without a doubt, a reliable graphics editor that can cater to the needs of professionals and hobbyist in various domains.
