FreeCAD is a parametric 3D computer-aided design (CAD) modeling application designed primarily for the creation of real-world objects. Parametric modeling is a type of modeling in which parameters control the geometry of the 3D objects you construct. 

Designers can use this open-source engineering CAD system to build and alter various objects in order to generate production-ready drawings. Creators can use FreeCAD to change a product’s dimensions, sketch geometry-constrained 2D designs, and run formula-based models with the help of an integrated spreadsheet. 

You can use the technical drawing module to create 2D views of 3D models, execute graphical procedures, and save files in SVG or PDF formats.

For more information about FreeCAD’s capabilities, let’s take a look at the feature list below. 

Features That Are Unique To Freecad

Mind Blowing Tool For Converting Ideas Into Realities

FreeCAD is primarily intended for the creation of real-world objects. Everything you do in FreeCAD is measured in real-world units, whether they’re microns, kilometers, inches, or feet, or a mix of them. 

It is also a dynamic 2D drafting toolkit that allows you to produce detailed drawings that can be submitted to the printer right away without any changes. This module can also be used to create templates and guides for you to follow as you build your 3D models.


FreeCAD may be scaled to the functionality you require using a modular setup. Plugins can be used to extend the functions. You can also use its Python interpreter, as well as external and macro scripts, to customize and expand its features. 

From the built-in Python interpreter, macros, or external scripts, you can access almost any part of FreeCAD, including geometry creation and transformation, 2D or 3D representation of that geometry (scenegraph), and even the FreeCAD interface.

Intuitive Interface 

The dashboard and workbenches can be customized and are well-organized. You have complete control over which tools are displayed. It’s simple to manage the interface, geometry, and rendering thanks to the embedded Python interpreter and open API. With Open CASCADE technology, FreeCAD enables complicated design specs for compound structures like breps, surfaces, and nurbs. 

Integrated Spreadsheet 

FreeCAD is a built-in and completely integrated spreadsheet solution that allows you to develop formula-based models and manage your workflow from a single location. 

3D Modeling

You may customize every parametric model to your exact specifications using a complete 3D modeling platform. For a more realistic modeling experience, you can utilize Open CASCADE technology to construct sophisticated 3D parametric objects that react to other models in your build.

The most astonishing aspect of this software is that it includes Python scripting and C++ programming, which allow you to quickly construct and design models, as well as an option for extensions. Its FEM feature and model export formats are really useful, and we use it on both Linux and Windows systems; it is open-source software with a fantastic user interface. 

Supports File Format

The FreeCAD Standard file format is FreeCAD’s primary file format. It’s a normal zip file that organizes files into a specific folder structure.  The Document.xml file contains the definitions for all geometric and parametric objects.

The visual representation details of items are then stored in GuiDocument.xml. Object brep-files and thumbnails of drawings are among the other files. 

And There Are a Lot More Wonderful Features

FreeCAD provides you with all of the necessary tools to meet your requirements. Modern FEA tools, experimental CFD, dedicated BIM, Geodata, or CAM/CNC workbenches, a robot simulation module for studying robot movements, and many more features are included. FreeCAD is a general-purpose engineering toolkit Swiss Army knife.

The Experience of Working with FreeCAD

Anyone who has used practically any other CAD software previously will find FreeCAD to be highly familiar. That isn’t to imply the user interface will remain the same, but the design process and how you interact with your workpiece will be similar.

When working with FreeCAD, you’ll mostly be dealing with the faces, edges, and vertices of your model (overall, its topology). However, if you prefer, FreeCAD also allows you to apply constructive geometry methods. You’ll get access to a variety of powerful procedures, including:

  • Extrusion is the process of stretching the surface of an object outward.
  • Edge transitions are known as chamfers.
  • Bevels are angles cut into an edge.

Hej mitt namn är Jakob och är 41 år gammal. Jag gillar att skapa saker i CAD. Använder mest FreeCAD och Fusion 360, men har testat de flesta CAD-program. Jag programmerar också i c#, python och Java. Skapar även appar i Android. Tycker även om fraktaler och att fotografera. Långa promenader i naturen är också skönt.
