About the 3D Modeling Software FreeCAD FreeCAD is a popular open source design software for creating 3D models of real-life objects.

Best of all it but you already know this it comes for free (just download it from on the FreeCAD website ) The CAD in its name simply stands for Computer-Aided Design.

FreeCAD is a 3D design program that allows you to easily navigate and modify your 3D model by browsing back into the model history and changing its individual elements.

It can be used on Windows, Mac and Linux, and reads and writes many open file formats including popular 3D printing formats such as STL, OBJ, and DAE.

This 3D modeling software is most suitable for geometric designs, such as precise technical parts, replacement parts, gadgets, cases, scale models, etc.

Enough of the small talk were here to design Lets get started with the FreeCAD tutorial FreeCAD Tutorial Part 1: Creating and Editing Primitives FreeCAD comes with several work benches.

These are basically a pre-defined set of tools that you are going to use.

For example, you can create a draft by choosing the Draft work bench.

However, we will start by using the Part work bench because we are here for creating a real physical object In the video below, your instructor Bram will first show you the very basics: how to choose the Part workbench, how to start your first project, how to navigate (press Alt left mouse button), how to add basic primitives (a box, a cylinder, etc.), and how to change the size, radius, and position of these primitives (under the menu Property).

FreeCAD Tutorial Part 2: Subtracting and Combining Primitives In this second video, Bram will teach you some more tricks on how to use primitives.

Youll also learn how to subtract different primitives from each other with the cutout tool.

For example: if you place a cylinder within a box and subtract them, the box will have a cylinder-shaped hole.

Changing the height and radius of it will now affect the height and radius of the hole.

You will also learn the opposite of subtracting two primitives: combining them.

You can do this by selecting both elements and clicking on the Make a union of several shapes button.

FreeCAD Tutorial Part 3: Creating A 2D Sketch For creating more complicated designs, Bram prefers to create two-dimensional sketches first.

He switches the work bench to Part Design and shows you how to set the best sketch orientation (XY-Plane).

If you draw straight lines, FreeCAD will notice this and will constrain them immediately for your convenience which means that the line will be perfectly parallel with the horizontal or vertical axis.

Furthermore, you need to precisely define the length of each line by selecting it and choosing the Make a dimension tool.
