Free Gear Generator for Fusion 360 | Clean 2D DXF Sketches for 3D Modeling

Stop struggling with buggy Fusion 360 spur gear scripts. GearDXF creates precision 2D closed-loop DXF profiles that import cleanly into Autodesk Fusion 360 sketches with zero unconstrained curve errors, ready for 1-click extrusion into production-grade 3D solid bodies.

Key Features

• AutoCAD R12 compatible DXF output optimized for Fusion 360 sketch engine
• Continuous closed-loop profiles: no broken loops or missing face boundaries
• Supports complex assemblies: spur gears, internal ring gears, and linear racks
• Custom backlash, center bore diameters, keyways, and spoke cutouts
• Simulate rotation and gear reduction kinematics before modeling
• 100% free web tool with no Autodesk App Store plugins required

Frequently Asked Questions

How do I import a GearDXF file into Fusion 360?

In Fusion 360, click Insert > Insert DXF. Select a construction plane, choose your downloaded GearDXF file, and ensure units match (millimeters or inches). Click OK, then press "E" to Extrude the gear profile.

Why use GearDXF instead of the built-in SpurGear Python add-in in Fusion 360?

The native add-in in Fusion 360 only creates basic external spur gears, often fails with complex parameters, lacks kinematic simulation, and cannot design internal ring gears or linear racks.

Can I assemble multiple gears in Fusion 360 using GearDXF?

Yes! GearDXF calculates and displays the exact center distance between gears. In Fusion 360, create Revolute Joints spaced by that exact distance to simulate physical gearing.
