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:
- Select one or more corner vertex(es).
- Activate the SheetMetal AddRelief command using one of the following:
- The SheetMetal AddRelief button.
- The SheetMetal → Make Relief menu option.
- The keyboard shortcut: S then R
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.
- Part Extrude from:
- A Draft Rectangle.
- A Draft Wire.
- A Sketch.
- 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.
- PartDesign Pad from a Sketch.
- Use PartDesign Thickness to create a shell object from the solid (Typically with the thickness value of the sheet metal).

A SheetMetal Relief object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties and its label has a default value:
{{Properties_Title|Base}}
-
Label|String: Default value: The user editable name of this object, it may be any arbitrary UTF8 string.
-
Base Feature|Link|hidden: Base Feature. Link to the parent feature.
-
_Body|LinkHidden|hidden: Hidden link to the parent body.
{{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}}.
