I made a script for Alibre that generates mathematically accurate internal and external gears. Unlike the example script, it uses a true trochoid (undercut shape) and an involute profile.
To keep things simple, the script creates (or replaces) a sketch and produces a single tooth.
Additionally, the script supports profile shifting (a technique commonly used to avoid undercutting).
I’ll continue updating the script, mainly to add variable support (for easier sketch modification and integration with child features), as well as bug fixes.
All the resources are available in the GitHub repository ( linked as resource information URL)
In the repository, you can also find visualization and debugging tools.

If you have a moment to comment or leave a review, I’d really appreciate it! I’ve put a lot of time into this project, and I’d love for it not to get buried in the forum eheh.
