The interface has transitioned from a rigid, sidebar-heavy layout to an intuitive, node-based or multi-window canvas workspace. Key UI improvements include:

Accurate gear design hinges on getting the math right. For each gear, you can define:

The Beta version introduces several highly requested tools that expand the software's capabilities far beyond simple spur gears.

To get the most out of the , follow these pro-tips:

The benefits of using Gear Generator 2 Beta are numerous. Here are just a few:

While the original tool focused on involute spur gears, the beta expands the selection to include additional types, such as and herringbone‑style teeth (though bevel gears are still not supported). A wider variety of pressure angles, modules, and tooth counts are available, making it easier to simulate real‑world mechanical systems.

The beta version has received generally from the hobbyist and maker community, especially for its planetary gear support. The ability to create complex layouts without installing any software is a major advantage.

: The system currently supports metric DIN standard gears. If you're designing for 3D printing, the tool generates a true 3D geometry, though it does not create mechanical joints or constraints—only the gear bodies.
