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:

1. SheetMetal AddRelief
2. SheetMetal AddJunction
3. SheetMetal AddBend

Make Relief - cut off corners

Usage

1. Select one or more corner vertex(es).
2. 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.
3. The Add Corner Relief on Solid Task panel opens (introduced in version 0.5.00).
4. Optionally press the Select button to add more vertices.
   • Press the Preview button to finish the selection and display the changes.
5. Optionally adjust the parameters in the Task panel.
6. Press the OK button to finish the command and close the Task panel.
7. A CornerRelief object will be created consisting of one new corner relief at each selected vertex.
8. 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:

1. Create a solid using either:
   • Part Box.
   • Part Extrude from:
     • A Draft Rectangle.
     • A Draft Wire.
     • A Sketch.
2. 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:

1. Create a solid using either:
   • Additive Box.
   • PartDesign Pad from a Sketch.
2. Use PartDesign Thickness to create a shell object from the solid (Typically with the thickness value of the sheet metal).

Properties

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:

Parameters

• Database Object (LinkSub): "Base Object". Links to the corner vertexes defining relief positions.
