The SheetMetal AddJunction command creates open junctions between two sections (walls/flanges) of a sheet metal object. Without these junctions sheet metal sections connected to the same base will not be unfoldable.
This command is the second of three steps to convert a shell object made with the Part Workbench or PartDesign Workbench into an unfoldable sheet metal object:
Make Junction - cut edges open
- Select one or more edge(s).
- Activate the SheetMetal AddJunction command using one of the following:
- The SheetMetal AddJunction button.
- The SheetMetal → Make Junction menu option.
- The keyboard shortcut: S then J.
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.
See SheetMetal AddRelief for hints about creating shell objects of cuboids.
