Beta testers get early access to the Pro Lab tab, which includes two experimental tools:
The dev team has included community-driven presets. You can now spawn a "LEGO Technic compatible" gear, a "Herringbone" gear, or a "NEMA 17 stepper mount" gear in seconds.
| Issue | Workaround | |-------|-------------| | Undercut not visualized | Beta shows ideal tooth form. Enable “show undercut warning” in settings. | | STEP export fails for internal gears | Use DXF + extrude manually in CAD. | | Herringbone mirror glitch | Set “helix angle” same for both directions, then adjust “gap” > 0. | | Bevel gear cone angle | Beta only does straight bevels (not spiral). Cone angle = 45° default; recalc using pitch cone. | | Unit confusion | Everything is metric (mm, module). For inches: design in mm, scale 25.4× in CAD. |
If you want, I can produce: a ready-to-use JSON project file for the example above; a STEP/STL export checklist; or a short CLI command sequence for generating and exporting that gear—tell me which.

This updated version focuses on precision, user experience, and expanded export capabilities, allowing users to transition from a digital concept to a physical prototype with unprecedented ease. Evolution of the Interface
The most immediate change in the Gear Generator 2 Beta is the modernized workspace. The developers transitioned from a cluttered sidebar layout to a more intuitive, modular design. Users can now manipulate gear properties through dynamic sliders or direct numerical input, with changes reflecting instantly in a real-world scale preview. This real-time feedback loop is essential for understanding how adjustments to the pressure angle or module affect the tooth profile and overall meshing efficiency. Enhanced Parametric Control
At its core, the software remains a parametric powerhouse. The Beta introduces deeper control over specific mechanical variables: If you want, I can produce: a ready-to-use
Tooth Profile Customization: Precise control over involute curves to minimize friction.
Spaced Meshing: Improved algorithms for calculating the center distance between multiple gears.
Internal Gear Support: A much-requested feature allowing for the creation of planetary gear sets.
Dynamic Hubs and Spokes: Options to add weight-reducing cutouts or reinforced mounting points directly within the tool.
These features ensure that the generated gears are not just visual representations but are mathematically sound components ready for real-world application. Integrated Simulation Tools
One of the standout features of the Beta is the animation and simulation engine. Users can input a specific RPM (rotations per minute) for the "driver" gear and observe how the torque and speed translate through a complex train. The software provides a live data overlay showing the gear ratios and output speeds at every point in the system. This allows designers to catch potential interference issues or velocity mismatches before they ever send a file to a 3D printer or CNC machine. Exporting and Manufacturing Compatibility
Precision in design is useless without compatibility in manufacturing. Gear Generator 2 Beta expands its export suite to support a wider range of workflows. Users can export their designs as SVG files for laser cutting, or high-fidelity DXF files for industrial machining. Furthermore, the Beta includes improved 3D export options, ensuring that the STL files generated are "manifold" and ready for slicer software without requiring mesh repairs. The Beta Community and Future Outlook
As a Beta release, the software relies heavily on user feedback to refine its algorithms. The current version includes a community portal where users can share their gear templates and motion assemblies. This collaborative environment has already led to faster bug reporting and the implementation of niche features like "cycloidal" gear profiles for high-reduction robotics applications.
Whether you are designing a custom clockwork mechanism, a high-torque gearbox for a drone, or an educational model for a classroom, the Gear Generator 2 Beta provides a professional-grade toolkit accessible from any modern web browser. It removes the steep learning curve associated with traditional CAD software, making mechanical excellence accessible to everyone. AI responses may include mistakes. Learn more

For the uninitiated, Gear Generator is a web-based parametric design tool. Unlike CAD software that requires you to manually draw involute curves (a complex mathematical process), Gear Generator automates the geometry. You input the numbers—teeth, module, pressure angle—and the software spits out a precise SVG, DXF, or STL file.
Gear Generator 2 Beta takes this concept and injects it with steroids. Currently in its testing phase, the beta focuses on three core pillars: Speed, Multi-Gear Networks, and Real-Time Physics.
