FreeCAD

FreeCAD is a free open source 3D parametric modeling tool, which allows users to design three-dimensional objects of any size. Parametric modeling allows you to easily modify any design through the change history of your project, meaning you can change or alter parameters with just one click.

Design all types of elements and objects

FreeCAD's overriding goal is to help you design objects that can be implemented in the real world. Everything done on the app uses measurements and units applicable to the real world which, of course, you will be able to set: centimeters, inches, kilometers, feet, etc. Once you have finished a project, simply export the result in your preferred format. You can export a project to use in other 3D modeling apps, and you can even create patterns to print any of your works in a 3D printer.

Learn to work with parametric objects

One of the great advantages of FreeCAD is that all objects created with it are natively parametric. What does this mean? Quite simple, its form is entirely based on easily recalculable properties, such as numbers, text and even other smaller objects. As a result, any change made to an object will be recalculated instantly, altering the other corresponding elements, and recorded in the change history. This provides you with the opportunity to preserve the integrity of your creations and, more importantly, the ability to recover any previous state of a project if needed.

Compatible with a host of formats

It is important for 3D modeling software to be compatible with the most common formats. In this respect, FreeCAD stands out above the rest. You can import and export models and projects in over a dozen different formats, including: STEP, IGES, OBJ, STL, DWG, DXF, SVG, SHP, DAE, IFC, OFF, NASTRAN, VRML, OpenSCAD CSG, and FCStd.

Download FreeCAD if you are looking for comprehensive 3D modeling software. The app not only offers an impressive range of features, but also provides you with a number of tutorials and other facilities to teach you how to perform any operation. Absolutely must-have software.
