SheetMetal AddJunction

Description

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:

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

Usage

1. Select one or more edges.
2. There are several ways to invoke the command:
   • Press the Make Junction button.
   • Select the SheetMetal → Make Junction option from the menu.
   • Right-click in the Tree view or the 3D view and select the SheetMetal → Make Junction option from the context menu.
   • Use the keyboard shortcut: S then J.
3. The Add Junction Parameter Task panel opens (introduced in version 0.5.00).
4. Optionally press the Select button to add more faces.
   • 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 Junction object will be created consisting of one opening at each selected edge.
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.

• See SheetMetal AddRelief for hints about creating shell objects of cuboids.

• Junction in this case is not the result of this tool, which is a gap between adjacent planar faces, but rather describes the location where two planar faces of the finished real world object meet, to be welded, for example.

Properties

See also: Property editor.

A SheetMetal Junction 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 edges defining gap/junction positions.

• gap|Length: \"Junction Gap\". Default: {{value|2,00 mm}}.Size of gap/junction to be added.
