In this tutorial, you will learn how to import an STP CAD file to Blender using FreeCAD, a free and open-source 3D software.

What is an STP file?

An STP file is a 3D assembly file that contains data about the shape and geometry of a product or a component. It is used by various mechanical design programs, such as Autodesk Fusion 360, FreeCAD, or TurboCAD.

You will learn how to convert your STP file to glTF, a format that is compatible with Blender, and how to import it to Blender and adjust its size. By the end of this tutorial, you will be able to use your 3D model in Blender for any purpose you want, such as rendering, animation, or simulation.

Step 1: Convert your STP file to glTF

    Thanks for this simple tutorial. It removes the need to download Add-Ons in Blender that are complex to use. It also solved a problem I was having as a complete newb in FreeCad.
