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)

Junction applied to corner

Usage

Second step to convert a hollow cuboid (shell object) into an unfoldable SheetMetal object:

Cut the edges open
  1. Select one or more edge(s)
  2. Activate the Make Junction command using the:
    • Make Junction button
    • SheetMetal → Make Junction drop down menu
    • keyboard shortcut: S then J

Notes

Note: The tools Make Relief, Make Junction, and Make Bend work best with hollow cuboids i.e. shell objects having a constant thickness and all angles between their faces are 90°.

See Make Relief Notes 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.
