Frequently Asked Questions

Why are GearDXF DXF files preferred over generic generators?

Many online generators export fragmented line segments with microscopic gaps that trigger CAM errors. GearDXF creates continuous, single-loop closed polylines ready for immediate toolpath generation.

How do I import the exported DXF into SolidWorks?

In SolidWorks, open a new part, select a sketch plane, click Insert > DXF/DWG, and choose Import to a new 2D sketch. You can then immediately apply an Extruded Boss/Base.

Does the DXF export include center markers and pitch circles?

Yes, you can toggle labels, pitch circles, and center marks on or off in the export panel depending on whether you need pure cutting contours or engineering drawings.
