SheetMetal Unfold

Description
The SheetMetal Unfold tool unfolds the metal sheet.


 * [[Image:Involute-Gear example.png]]

Usage

 * 1) Switch to the [[Image:Sheetmetal_workbench_icon.svg|22px]] SheetMetal Workbench.
 * 2) Invoke the command several way:
 * 3) * Press the FCGear_InvoluteGear.svg Create an Involute gear button in the tool bar.
 * 4) * Using the.
 * 5) Change the gear parameter to the required conditions (see  below).

Data

 * : Placement is the location and orientation of an object in space.
 * : User name of the object in the Tree view.


 * : Pitch diameter (not changeable, is calculated automatically).


 * : With the helix angle β a helical gear is created (positive value → rotation direction right, negative value → rotation direction left).
 * : Default is 0,25 (see also the information in ).
 * : creates a double helix gear (see also the information in )
 * : Default is 0,00. This value is used to change the tooth height.
 * : Value of the gear width.
 * : Module is the ratio of the reference diameter of the gear divided by the number of teeth (see also the information in ).
 * : Default is 6, change of the involute profile. Changing the value can lead to unexpected results.
 * : If helix angle β is given and is enabled, gear parameters are internally recomputed for the rotated gear.
 * : Default is 0,00, generates a positive and negative profile shift (see also the information in ).
 * : generates a simplified display (without teeth and only a cylinder in pitch diameter).
 * : Number of teeth (see also the information in )
 * : changes the profil of the tooth root (see also the information in ).


 * : Default is 20 (see also the information in ).


 * : Default is 0,00. Backlash, also called lash or play, is the distance between the teeths at a gear pair.
 * : backlash decrease or  backlash increase (see also the information in ).
