Usage

 * 1) Switch to the [[Image:FCGear_workbench_icon.svg|16px]] FCGear Workbench.
 * 2) There are several ways to invoke the command:
 * 3) * Press the button in the toolbar.
 * 4) * Select the option from the menu.
 * 5) Change the gear parameter to the required conditions (see  below).

Properties
An FCGear CycloidRack object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:


 * : (number of points for spline), default is 15.


 * : Default is, If enabled, the total length of the rack is teeth x pitch, otherwise the rack starts with a tooth-flank.
 * : Value of the gear width.
 * : Number of teeth.
 * : Default is . Thickness of the uncut part of the rack.


 * : Default is . Pitch in the transverse plane. (read-only)


 * : Default is . Diameter of the rolling circle of hypocycloid, normalized by the  (see also the information in Notes).
 * : Default is . Diameter of the rolling circle of epicycloid, normalized by the  (see also the information in Notes).


 * : Default is.
 * : Default is.


 * : Default is . With the helix angle β a helical gear is created (positive value → rotation direction right, negative value → rotation direction left).
 * : Default is . creates a double helix gear (see also the information in Notes).


 * : Default is . For racks the module equals the pitch and so is the distance between corresponding points on adjacent teeth (see also the information in Notes).


 * : Default is . If the rack is drawn with a constant number of teeth to avoid topologic renaming.


 * : Default is (see also the information in Notes).
 * : Default is . Additional length of the tip of the teeth, normalized by the.
