Free Gear Generator for SolidWorks | Precision 2D Involute DXF Profiles

Generate true involute gear profiles for Dassault Systèmes SolidWorks in seconds. Skip the complexity of Toolbox licensing and mathematical curve equations. Configure your gear in GearDXF, export an R12 DXF, and import it directly into a SolidWorks 2D sketch for immediate extrusion.

Key Features

• Clean 2D sketch DXF import into SolidWorks without self-intersecting loops
• Accurate base circle, pitch circle, dedendum, and addendum involute curves
• Includes drive keyways, center shaft bores, and weight-reducing spokes
• Works with standard Metric Module and Imperial Diametral Pitch systems
• Verify gear reduction ratios with real-time visual simulation
• 100% free with no SolidWorks Toolbox add-in license required

Frequently Asked Questions

How do I import the DXF into a SolidWorks part file?

In SolidWorks, open a Part file, select a plane (e.g. Front Plane), go to Insert > DXF/DWG, select your GearDXF file, choose "Import to that sketch", verify units, and click Finish.

Does SolidWorks Toolbox create true involute gears?

No! SolidWorks Toolbox gears use simplified visual approximations for tooth flanks to save graphics memory. GearDXF creates true mathematical involute curves required for real CNC manufacturing.

Can I edit the imported sketch in SolidWorks?

Yes, the imported geometry is a standard 2D sketch entity that you can dimension, constrain, fillet, or pattern in your SolidWorks feature tree.
