The [[Image:SheetMetal Junction.svg|24px]] SheetMetal Junction tool.
The [[Image:SheetMetal_AddJunction.svg|24px]] [[SheetMetal_AddJunction|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.

{{Emphasis|Note}}: The workbench does not have a tool to create a base plate, so you need to start your model with one of the following methods:

:* Method 2: An extruded solid made with [[File:Part_Extrude.svg|24px]] [[Part Extrude]] from either a:

::* [[File:Draft_Wire.svg|24px]] [[Draft Wire]] or a
::* [[File:Sketcher_NewSketch.svg|24px]] [[Sketcher NewSketch|Sketch]]
::* Use [[Image:Part_Thickness.svg|24px]] [[Part Thickness]] to create shell ({{Emphasis|Typically with the thickness value of the sheet metal.}})
:* Method 3: [[File:PartDesign_Body.svg|24px]] [[PartDesign Body]] containing either an

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

Make Junction - cut edges open

Usage

  1. Select one or more edge(s).
  2. 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.

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.

Properties

See also: Property editor.

A SheetMetal Junction 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:

Data

Base

  • DataLabel (String): Default value: Junction (+ a sequential number for second and following items).
    The user editable name of this object, it may be any arbitrary UTF8 string.
  • Data (hidden)Base Feature (Link): Base Feature. Link to the parent feature.
  • Data (hidden)_Body (LinkHidden): Hidden link to the parent body.

Parameters

  • Database Object (LinkSub): "Base Object". Links to the edges defining gap/junction positions.
  • Datagap (Length): "Junction Gap". Default: 2,00 mm.Size of gap/junction to be added.
