What is Autodesk Fusion 360? Easy
Autodesk Fusion 360 is a cloud-based 3D CAD, CAM, and CAE software platform. It allows engineers, designers, and manufacturers to design, simulate, and manufacture products within a single integrated environment.
Unlike traditional CAD tools that separate modeling and simulation, Fusion 360 combines parametric modeling, direct modeling, rendering, simulation, and CAM workflows in one system. Because it is cloud-connected, files can be accessed from multiple devices and teams can collaborate easily.
It is widely used in product design, mechanical engineering, industrial design, and CNC manufacturing.

What are the main workspaces in Fusion 360? Easy
Fusion 360 is divided into multiple workspaces that serve different purposes:
- Design – For creating 3D models and assemblies.
- Render – For photorealistic visualization.
- Simulation – For stress and thermal analysis.
- Manufacture (CAM) – For CNC toolpath generation.
- Drawing – For creating 2D technical drawings.
Each workspace is specialized but works seamlessly with others, making it efficient for complete product development.
3
What is Parametric Modeling in Fusion 360? Easy
Parametric modeling means that model dimensions and features are controlled by parameters and can be modified later.
