If that doesn't suit you, our users have ranked more than 25 alternatives to Autodesk Fusion and 13 is open source so hopefully you can find a suitable replacement. Other interesting open source alternatives to Autodesk Fusion are FreeCAD, OpenSCAD, Dune 3D and MeshLab.
A comprehensive open-source 3D software suite for modeling, UV unwrapping, texturing, rigging, and animating. It supports renderings, simulations including fluid and cloth dynamics, complex compositing, video editing, and Python scripting, running across all major operating systems.
A powerful open-source parametric 3D modeler ideal for mechanical engineering, supporting Python scripting, running on Windows, Linux, and Mac, with modular architecture allowing extensive adaptability and use with scientific computing libraries.
OpenSCAD is a software for creating solid 3D CAD objects. It is free software and available for Linux/UNIX, MS Windows and MacOS.
Dune 3D operates as a parametric 3D Computer-Aided Design (CAD) software. It provides users with the capability to sketch and constrain both in 2D and 3D dimensions. Furthermore, it allows for the addition of chamfers and fillets to designs.
System for processing and editing 3D triangular meshes, provides a set of tools for editing, cleaning, healing, inspecting, rendering, texturing and converting meshes.

It's not the same goal. Autodesk is for engineering, blender is for animation/art. Both are great but they are not for the same job
