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:
- Passare nell'ambiente
SheetMetal. - Iniziare con una lastra di base o un foglio, selezionare uno o più bordi che devono ricevere una piega.
- Cliccare sullo strumento Bend per aggiungere una piega.
Task Panel
A Task Panel with four tabs was introduced in 0.6.00

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:
- Metodo 1:
Cubo di Part - Metodo 2: Un solido estruso realizzato con
Estrudi di Part da un:
Rettangolo di Draft o una
Polilinea di Draft o uno
Schizzo- Usare
Spessore di Part per creare un solido (Tipicamente con il valore dello spessore della lamiera.)
- Metodo 3:
Corpo di PartDesign contenente un
cubo additivo o un
pad prodotto da uno schizzo.- Usare Spessore di Part per creare un solido (Tipicamente con il valore dello spessore della lamiera.)
- Metodo 1:
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
- Create a blank
- Select the outline sketch
- Press the
Make Base Wall button
or use the keyboard shortcut: C then F
(The blank is padded in z direction
- Select the outline sketch
- Add walls to the outline edges
- Select the blank's outline edges
- Press the
Make Wall button
or use the keyboard shortcut: W
- 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)
- Select the blank's outline edges
- Add some more walls
- Select the tray's upper outside edges
- Press the Make Wall button
or use the keyboard shortcut: W
- The walls are a bit too long (but nicely trimmed) and so the length property has to be set to a lower value
- If you like the folds swing outward set the invert value to true
- Select the tray's upper outside edges
Done!
