SheetMetal AddJunction

Description
The Make Junction command starts the second of three steps to convert a shell object made with tools of the Part or PartDesign workbench into an unfoldable SheetMetal object.

As long as three faces meet at a corner and each face is joined to both other face the object can't be unfolded, and so one joint has to be cut open.

Folding a corner needs two bends; and the two remaining edges meet at a junction, thus the naming Make Junction.
 * (Junction sounds odd to me. Native speakers please review)



Usage
To add junction to corner of corner:
 * 1) Start with a base plate or sheet, select a corner vertex to apply relief
 * 2) Click on the [[Image:SheetMetal Junction.svg|24px]] Junction tool to add a junction cut to corner.


 * 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 1: Part_Box.svg Part Cube
 * Method 2: An extruded solid made with Part_Extrude.svg Part Extrude from either a:
 * Draft_Rectangle.svg Draft Rectangle or a
 * Draft_Wire.svg Draft Wire or a
 * Sketcher_NewSketch.svg Sketch
 * Use [[Image:Part_Thickness.svg|24px]] Part Thickness to create shell
 * Method 3: PartDesign_Body.svg PartDesign Body containing either an
 * PartDesign_AdditiveBox.svg additive box or a
 * PartDesign_Pad.svg PartDesign Pad made from a Sketcher_NewSketch.svg Sketch.
 * Use PartDesign Thickness.svg PartDesign Thickness to create shell


 * If you start with a PartDesign_Body.svg PartDesign Body, you can mix Sheet Metal features with PartDesign features such as PartDesign_Pocket.svg pockets or PartDesign_Hole.svg holes.

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:
