# CAD export

> [HTML Version](cad-export2.html)

Several graphics can be selected in menu Graphics->CAD. The tooth form in the transverse section is exported using Bezier curves of accuracy better than $10^{-4}m_n\cdot\cos(\beta)$. This transverse section is then extruded along the helix for a helical gear. The accuracy of the extrusion depends on the CAD system.

Currently no profile corrections and flank line corrections are considered.
