Softwares
Fusion 360 (Free)
Autodesk Fusion 360 is a cloud centered alternative to Inventor. With much of the same functionality, alongside some additional tools, Fusion 360 makes it easier for teams to collaborate & share files across projects. Fusion 360 is also cross platform making it accessible regardless of the computer that is being used.
This parts library features every VRC legal part currently available, and will continue to be updated as new parts get released. This library is the second iteration of the original Fusion 360 Library.
Installation
To install the parts library, download the zip file and follow this video tutorial.

Changes
Most notably, the Fusion 360 Add-In is no longer supported, however there are plans to re-implement the add-in in the future. There are now files for every length of structure, similar to the Inventor library, and all motion pieces that support inserts now have individual files for every type of insert, including no insert. Additionally, every available length for spacers, screws, and standoffs are now available. You can view the full changelog here.
Onshape (Free)
OnShape is a cloud-based CAD program created to provide collaborative and accessible design capabilities, eliminating the need for traditional software installations and hardware limitations. It allows multiple users to work on the same design simultaneously, making it ideal for team-based projects and remote collaboration. OnShape is best used for real-time collaboration, streamlined workflow, and easy access to design files from any device with an internet connection.
OnShape does not require any software to be installed to a computer making it a great option for Schools & students without access to individual personal computers.
The Youtube playlist below will do a great job at getting anyone started with the program & building a first robot.

Inventor (Robotics Room Computers)
Autodesk Inventor is a very powerful program that is actively used by professionals in industry allowing for skills developed for Vex to be applied later on. Inventor has a robust set of tools that allow for almost any functionality desired for Vex Robotics design. Inventor is a great choice for Vex students due to its ease of assembly & application of industry tools. Inventor's biggest weakness is being Windows only, and needing local file storage.
This library includes every length of metal, commonly used cut metal, construction circles for ease of constraining, and parametric hardware.
Library 1.4 is a large update with a lot of new parts, a lot of fixed textures, and a new set of metals structure that fixes the inaccuracies with the published Vex parts. There are also some naming inconsistencies that are fixed. As well as quality-of-life fixes for pneumatics, hinges, chain generation, and for rendering. It is NOT compatible with previous versions
Parts Library Download The recommended file structure is to have a CAD folder anywhere on your computer and place the latest release in this folder. Every new robot you create will be a new folder in the CAD folder.
It is often helpful to use Github Desktop (Or Another Git Client) to download the library. Downloading a .Zip has lead to missing parts or corrupted files.
SolidWorks (Free)
Solidworks is by far the most commonly used of the listed programs when it comes to industry. This is because of the high skill ceiling and numerous tools that're featured in Solidworks. That being said, it thereby has the hardest learning curve and can be quite overwhelming to new users. It is not recommended as a first CAD program, but can be picked up once core skills are understood in other programs.
Latest Release: 1.1.0 This library includes all VEX parts (as of 2/17/2023) for ease of use when CADing.
