The steps can vary significantly depending on the software. Most CAD software allows for the creation of splines with specific standards through:
The DIN 5480 standard dictates the geometry, dimensions, and gauging practices for involute splines based on reference diameters. Unlike other standards that use the pitch diameter as the starting point, DIN 5480 positions the at the center of the design framework. Key Characteristics of DIN 5480 Splines: Pressure Angle: Strictly 30°.
The "DIN 5480-2: Nominal and inspection dimensions" PDF is the primary source for all dimensional data. It contains extensive tables for each standard module, ranging from m = 0.5 mm to m = 10 mm. din 5480 spline dimensions pdf

The standard covers a comprehensive range of modules and tooth combinations. For instance, modules from and tooth counts from 6 to 82 are included. The dimension tables in the official standard (PDF) for modules like 0.5, 1, 2, 3, 4, 5, 6, 8, and 10 are the primary source for all required data. This public link is valid for 7 days
