SheetMetal AddWall

Description
The SheetMetal Bend tool Extends a wall from a side face of the metal sheet.

Usage
To add a Bend:
 * 1) Switch to the [[Image:Sheetmetal_workbench_icon.svg|22px]] SheetMetal Workbench.
 * 2) Start with a base plate or sheet, select a thin face representing the thickness of the metal sheet
 * 3) Click on the [[Image:SheetMetal_Bend.svg|24px]] Bend tool to add a bend.

Data

 * : Bend angle.
 * : Extends the wall on the left side.
 * : Extends the wall on the right side.
 * : Gap from the left side.
 * : Gap from the right side.
 * : Invert bend direction.
 * : Length of the wall.
 * : Bend miter angle on the left side.
 * : Bend miter angle on the right side.
 * : Bend radius.
 * : Rectangle or Round. Enabled only when a gap value is set.
 * : Relief depth. Enabled only when a gap value is set.
 * : Relief width. Enabled only when a gap value is set.
 * : K factor (also known as neutral factor) for the bend. Used to calculate bend allowance when unfolding.
 * : False (default) or True. If true, unfolds the bend.


 * : 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 ).
