==Description== <!--T:39-->
<!--T:4-->
The [[Image:SheetMetal_AddWall.svg|24px]] '''SheetMetal AddWall''' command creates flanges on selected edges of a base plate. By changing the {{PropertyData|angle}} property a flange it can be turned into a hem.


<!--T:1-->
<!--T:36-->
A '''flange''' consists of a 90° cylindrical bend and a planar strip (wall).

==Notes== <!--T:40-->

<!--T:7-->
To create a base plate use a closed 2D outline - preferably a [[File:Sketcher_NewSketch.svg|16px]] [[Sketcher NewSketch|Sketch]] - with the [[Image:SheetMetal_AddBase.svg|16px]] [[SheetMetal_AddBase|Make Base Wall]] command.

<!--T:41-->
Alternatively a base plate (blank) can be created with commands from the [[Image:Workbench_Part.svg|16px]] [[Part_Workbench|Part Workbench]] or [[Image:Workbench_PartDesign.svg|16px]] [[PartDesign_Workbench|PartDesign Workbench]].

<!--T:42-->
To create a blank with the [[Part_Workbench|Part Workbench]]:
# Create a solid using either:
#* [[File:Part_Box.svg|16px]] [[Part_Box|Part Box]].
#* [[File:Part_Extrude.svg|16px]] [[Part_Extrude|Part Extrude]] from:
#** A [[File:Draft_Rectangle.svg|16px]] [[Draft_Rectangle|Draft Rectangle]].
#** A [[File:Draft_Wire.svg|16px]] [[Draft_Wire|Draft Wire]].
#** A [[File:Sketcher_NewSketch.svg|16px]] [[Sketcher_NewSketch|Sketch]].
# Make sure one the dimensions of the Box or the extrusion distance equals the sheet metal thickness.

<!--T:43-->
To create a blank with the [[PartDesign_Workbench|PartDesign Workbench]]:
# Create a solid using either:
#* [[File:PartDesign_AdditiveBox.svg|16px]] [[PartDesign_AdditiveBox|Additive Box]].
#* [[File:PartDesign_Pad.svg|16px]] [[PartDesign Pad]] from a [[File:Sketcher_NewSketch.svg|16px]] [[Sketcher NewSketch|Sketch]].
# Make sure one the dimensions of the Box or the {{PropertyData|Length}} property of the Pad equals the sheet metal thickness.

<!--T:8-->
If you start with a [[File:PartDesign_Body.svg|16px]] [[PartDesign_Body|PartDesign Body]], you can mix SheetMetal features with PartDesign features such as [[File:PartDesign_Pocket.svg|16px]] [[PartDesign_Pocket|PartDesign Pocket]] or [[File:PartDesign_Hole.svg|16px]] [[PartDesign_Hole|PartDesign Hole]].

<!--T:30-->
==Notes==
{{Properties_Title|Parameters Ex2}}


<!--T:31-->
* {{Emphasis|clearance}}: At a gear pair, clearance is the distance between the tooth tip of the first gear and the tooth root of the second gear.
* {{PropertyData|Sketch|Link}}: "Sketch Object".
* {{Emphasis|double_gear}}: To use the double helical gearing the helix angle β ({{Emphasis|beta}}) for the helical gearing must first be entered.
* {{PropertyData|sketchflip|Bool}}: "Flip Sketch Direction". Default: {{FALSE}}.
* {{Emphasis|module}}: 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.
* {{PropertyData|sketchinvert|Bool}}: "Invert Sketch Start". Default: {{FALSE}}.
* {{Emphasis|shift}}: Profile shift is not merely used to prevent undercut. It can be used to adjust center distance between two gears. If a positive correction is applied, such as to prevent undercut in a pinion, the tooth thickness at top is thinner.
* {{Emphasis|teeth}}: If the number of teeth is changed, the pitch diameter also changes ({{Emphasis|dw}}).
* {{Emphasis|undercut}}: Undercut is used when the number of teeth of a gear is too small. Otherwise the mating gear will cut into the tooth root. The undercut not only weakens the tooth with a wasp-like waist, but also removes some of the useful involute adjacent to the base circle.
* {{Emphasis|pressure_parameter}}: 20° is a standard value here. The pressure angle is defined as the angle between the line-of-action (common tangent to the base circles) and a perpendicular to the line-of-centers. Thus, for standard gears, 14.5° pressure angle gears have base circles much nearer to the roots of teeth than 20° gears. It is for this reason that 14.5° gears encounter greater undercutting problems than 20° gears. Important. the pressure angle changes with a profile shift. Only change the parameter, if sufficient knowledge of the gear geometry is available.
* {{Emphasis|reversed_backslash}}: If there are several gears, pay attention to which gear the parameter is set for.

Description

The SheetMetal AddWall command creates flanges on selected edges of a base plate. By changing the Dataangle property a flange it can be turned into a hem.

A flange consists of a 90° cylindrical bend and a planar strip (wall).

Two selected edges → two flanges

Resetting the Dataangle property to about 180° in a second step will create a hem instead.

Two selected edges → two hems

Usage

  1. Select one or more edge(s) of a base plate.
  2. Activate the SheetMetal AddWall command using one of the following:
    • The Make Wall button.
    • The SheetMetal → Make Wall menu option.
    • The keyboard shortcut: W.

Notes

To create a base plate use a closed 2D outline - preferably a Sketch - with the Make Base Wall command.

Alternatively a base plate (blank) can be created with commands from the Part Workbench or PartDesign Workbench.

To create a blank with the Part Workbench:

  1. Create a solid using either:
  2. Make sure one the dimensions of the Box or the extrusion distance equals the sheet metal thickness.

To create a blank with the PartDesign Workbench:

  1. Create a solid using either:
  2. Make sure one the dimensions of the Box or the DataLength property of the Pad equals the sheet metal thickness.

If you start with a PartDesign Body, you can mix SheetMetal features with PartDesign features such as PartDesign Pocket or PartDesign Hole.

Example

A simple tray

Preparation

This tray is made of a rectangular blank with walls added to its outline edges. And so one outline sketch for the blank has to be prepared in advance.

Just a rectangular outline

Workflow

  1. Create a blank
    1. Select the outline sketch
    2. Press the Make Base Wall button
      or use the keyboard shortcut: C then F

      (The blank is padded in z direction

  2. Add walls to the outline edges
    1. Select the blank's outline edges
    2. Press the Make Wall button
      or use the keyboard shortcut: W
    3. If the fold is 90° down set the value of invert property to true to reverse the direction (and length to a lower value for smaller walls)


  3. Add some more walls
    1. Select the tray's upper outside edges
    2. Press the Make Wall button
      or use the keyboard shortcut: W

    3. The walls are a bit too long (but nicely trimmed) and so the length property has to be set to a lower value
    4. If you like the folds swing outward set the invert value to true

Done!
