Inventor is 3D CAD software for modeling and mechanical design. It allows you to associate individual parts and assembly drawings for manufacturing specifications. You can use these drawings to create a complete working model that simulates operation and performance in 3D.
AutoCAD is desktop-based design, drawing, drafting, and modeling software widely used to create building plans, service and design schematics, and other layouts that can be represented in both 2D and 3D.
Fusion 360 is cloud-based CAD/CAM/CAE software designed for mechanical engineers. It uses freeform modeling to create true 3D simulations for mechanical design, testing, and manufacturing.
