Free Gear CAD Generator | Parametric 2D Profiles for CAD Software

Save hours of tedious CAD sketch modeling. Instead of drawing involute equations and tooth profiles from scratch in SolidWorks or Fusion 360, configure your gear parameters in GearDXF in seconds and export an exact 2D CAD profile ready for instant 3D extrusion.

Key Features

• Eliminates complex manual equation-curve sketching in CAD
• True mathematical involute profiles with ISO/AGMA standard clearances
• Parametric control over module, pitch diameter, teeth, and pressure angles
• Compatible with Autodesk Fusion 360, SolidWorks, FreeCAD, and PTC Creo
• Live rotation and meshing animation to verify gear center distances
• 100% free tool with no login required

Frequently Asked Questions

Why should I use GearDXF instead of built-in CAD gear plugins?

Most native CAD gear plugins produce simplified approximations or require complex add-ins. GearDXF runs instantly in any browser, calculates true involutes, and provides real-time multi-gear kinematic simulation.

How do I calculate the center distance between two gears in CAD?

Center distance between two standard external spur gears is simply: Center Distance = (Module × (Teeth_1 + Teeth_2)) / 2.

Can I import multi-gear assemblies into CAD?

Yes, GearDXF lets you export nested multi-gear sets or assembled layouts as a single DXF file with correct relative spatial positioning.
