Descrizione

Lo strumento di piegatura di SheetMetal crea una piega sul bordo selezionato.

A flange usually consists of a 90° cylindrical bend and a planar strip (wall).

Two selected edges → two flanges

It is called a hem instead if the bend is roughly 180°.

Two selected edges → two mitered hems

Utilizzo

Per aggiungere una piega:

  1. Passare nell'ambiente SheetMetal.
  2. Iniziare con una lastra di base o un foglio, selezionare uno o più bordi che devono ricevere una piega.
  3. Cliccare sullo strumento Bend per aggiungere una piega.

Notes

Nota: questo ambiente non dispone di uno strumento per creare una piastra di base, quindi è necessario avviare il modello con uno dei seguenti metodi:

Proprietà

See also: Property View.

A SheetMetal Bend 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:

Example

A simple tray

Preparation

This tray is made of a rectangular blank with walls added to its outline edges. And so one outline sketch for the blank has to be prepared in advance.

Just a rectangular outline

Workflow

  1. Create a blank
    1. Select the outline sketch
    2. Press the Make Base Wall button
      or use the keyboard shortcut: C then F

      (The blank is padded in z direction

  2. Add walls to the outline edges
    1. Select the blank's outline edges
    2. Press the Make Wall button
      or use the keyboard shortcut: W
    3. If the fold is 90° down set the value of invert property to true to reverse the direction (and length to a lower value for smaller walls)


  3. Add some more walls
    1. Select the tray's upper outside edges
    2. Press the Make Wall button
      or use the keyboard shortcut: W

    3. The walls are a bit too long (but nicely trimmed) and so the length property has to be set to a lower value
    4. If you like the folds swing outward set the invert value to true

Done!
