 * : The value is the result of multiplication of . This means for the standard involute rack of FCGear: 15 * 3,14  is 47.12 mm. See also  further below.
 * : At a gear pair, clearance is the distance between the tooth tip of the first gear and the tooth root of the second gear.
 * : To use the double helical gearing the helix angle β for the helical gearing must first be entered.
 * : Using ISO (International Organization for Standardization) guidelines, Module size is designated as the unit representing gear tooth-sizes. Module (m): m = 1 (p = 3.1416), m = 2 (p = 6.2832), m = 4 (p = 12.566). If you multiply Module by Pi, you can obtain Pitch (p). Pitch is the distance between corresponding points on adjacent teeth. The result of the multiplication is displayed in
 * : Only change the parameter, if sufficient knowledge of the gear geometry is available.
