DXF SPLINE is used for the curve involute and trochoid curves in the dxf export
Added the Bezier curve generation for the spline profile for improved performance on imports into CAD software. Imports into CAD software are now much faster, and no longer load in the all points and each individual polyline. If your software does not support Bezier curves, the spline profile can be exported as a polyline using legacy mode.
2026-03-06Database lookup improvements
SplineCAD database lookup improvements. Added performance indexes to the database for faster lookup of spline data.
2026-02-21Single tooth space DXF export
Added the Single tooth space DXF export. Also improved the DIN 5480 shaft spline profile generation.
2026-02-11Custom Inspection Pins and Spans for ANSI B92.1
Added the Custom Inspection Pins and Spans for ANSI B92.1. It is using the actual tooth thickness and space widths to match the style of the other standards and for improved lookup for reverse engineering spline data.
2026-01-25ANSI B92.1 Min and Max Effective and Actual.
Added the Min and Max Effective and Actual tooth thickness and space width calculations to the ANSI B92.1 data tables. Added in the measurement over pins (MOP) and measurement between pins (MBP) range using the actual tooth thickness and space widths to match the style of the other standards and for improved lookup for reverse engineering spline data.
