ISO 4156 Major Diameter Calculation Fix
Fixed the ISO 4156 major diameter calculation to never exceed the table max. This is a clearance fit and the major diameter should not exceed the table max.
2026-07-30OAuth login for Microsoft Entra ID
Deployed Microsoft Entra ID to enforce Zero Trust conditional access, phishing-resistant MFA, and automated identity governance.
2026-07-29Add X profile shift to DIN 5480 spline profile generation and refined accuracy
Added the ability to select the X profile shift to the DIN 5480 spline profile generation to allow the user to select the tooth thickness they desire. Refined the accuracy of the DIN 5480 spline profile generation. Fixed some edge cases in the generation, the trochoid root curve is now more accurate.
2026-07-19Minor Corrections to the Internal Spline Profile Generation when a large profile shift is used
Corrected the generating angles of the shaper cutter root geometry so now all root geometry is correct when profile shifts are large.
2026-04-28DXF 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.
