Folding a corner needs two bends; and the two remaining edges meet at a junction, thus the naming Make Junction.

Description

The Make Junction command creates open junctions between two sections (walls/flanges) of a sheetmetal object. Without these junctions sheetmetal 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 SheetMetal object:

  1. Make Relief
  2. Make Junction
  3. Make Bend

Make Junction - cut edges open

Usage

  1. Select one or more edge(s).
  2. Activate the Make Junction command using one of the following:
    • The Make Junction 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.
