SheetMetal AddRelief
Description
The SheetMetal AddRelief command creates corner reliefs, cutouts, at the points where three sections (base plate/walls/flanges) of a sheet metal object meet. Without these reliefs the object will not be unfoldable.
This command is the first of three steps to convert a shell object made with the Part Workbench or PartDesign Workbench into an unfoldable sheet metal object:

Usage
- Select one or more corner vertex(es).
- There are several ways to invoke the command:
- Press the
Make Relief button.
- Select the SheetMetal →
Make Relief option from the menu.
- Right-click in the Tree view or the 3D view and select the Sheet Metal →
Make Relief option from the context menu.
- Use the keyboard shortcut: S then R.
- Press the
- The Add Corner Relief on Solid Task panel opens (introduced in version 0.5.00).
- Optionally press the Select button to add more vertices.
- Press the Preview button to finish the selection and display the changes.
- Optionally adjust the parameters in the Task panel.
- Press the OK button to finish the command and close the Task panel.
- A CornerRelief object will be created consisting of one new corner relief at each selected vertex.
- Optionally adjust the parameters in the Property editor.

Notes
The commands SheetMetal AddRelief,
SheetMetal AddJunction, and
SheetMetal AddBend work best with hollow cuboids i.e. shell objects with a constant thickness and only 90° angles between faces.
Shell objects can be created with commands from the Part Workbench or the
PartDesign Workbench.
To create a hollow cuboid with the Part Workbench:
- Create a solid using either:
-
[Part Box](wiki-test2.php?gitpage=Part_Box).
-
[Part Extrude](wiki-test2.php?gitpage=Part_Extrude) from: - A
[Draft Rectangle](wiki-test2.php?gitpage=Draft_Rectangle). - A
[Draft Wire](wiki-test2.php?gitpage=Draft_Wire). - A
[Sketch](wiki-test2.php?gitpage=Sketcher_NewSketch).
-
- Use
Part Thickness to create a shell object from the solid (Typically with the thickness value of the sheet metal).
To create a hollow cuboid with the PartDesign Workbench:
- Create a solid using either:
-
[Additive Box](wiki-test2.php?gitpage=PartDesign_AdditiveBox).
-
[PartDesign Pad](wiki-test2.php?gitpage=PartDesign_Pad) from a
[Sketch](wiki-test2.php?gitpage=Sketcher_NewSketch).
-
- Use
PartDesign Thickness to create a shell object from the solid (Typically with the thickness value of the sheet metal).
Properties
See also: Property editor.
A SheetMetal Relief object is derived from a Part Feature object or, if it is inside a PartDesign Body, from a PartDesign Feature object, and inherits all its properties. It also has the following additional properties:
Data
{{Properties_Title|Parameters}}
-
base Object|LinkSub: \"Base Object\". Links to the corner vertexes defining relief positions.
-
relief|Length: \"Relief Size\". Default: {{value|2,00 mm}}.
