Creates an unfolded 2D or 3Drepresentation of a sheet metal part.

Accessing the Command

command bar:  smunfold

menu bar:  Sheet Metal | Unfold Body

toolbar:  Sheet Metal |

ribbon: Sheet Metal | Flatten |

 

: smunfold

Prompts you in the command bar:

Select a flange or lofted bend face to start unfolding [Settings]: (Select the base flange of the sheet metal part.)

Select position of the unfolded body: (Specify a point in the drawing.)

Validate the unfolded body and select an option [save 2D geometry/save 3D geometry/export to Jetcam/Optimize bend annotations/Keep] <JetCam>: (Press Enter to keep the unfolded body in the drawing or choose an option.)

alidate the unfolded body and select an option [save 2D geometry/save 3D geometry/export to Jetcam/Keep] <Keep>:

Command Options

Option

Description

Settings

Allows to override the default unfolding settings.

Prompts you:

Select [lofted bend Tolerance/Form feature behavior] <Form feature behaviour> - select an option.

  • Lofted bend tolerance: Allows to specify the tolerance for lofted bends.
    Prompts you:
    Set tolerance for lofted bends straight edges determination
    - type a value.

  • Form feature behavior:  Allows to modify the value of the SMFORMFEATUREUNFOLDMODE system variable.
    Prompts you:
    Select form feature behaviour [Keep/Remove/Project/Contour/Symbol] <Symbol>
    - select an option.

  • Keep: Keeps the form features geometry on the unfolded representation.

  • Remove: Removes the form features geometry from the unfolded representation.

  • Project: Generates a form feature symbol by projecting the form feature edges on the flange plane.

  • Contour: Generates a form feature symbol by projecting an external contour and holes of the form feature on the flange plane.

  • Symbol: Copies the unfold symbol on  layer UNFOLD_SYMBOL_UP or layer UNFOLD_SYMBOL_DOWN depending on the form feature direction) to the unfolded representation.

Keep

Places the unfolded 3D solid in the current drawing.

Save 2D geometry

Saves the 2D geometry of the unfolded metal part as a separate drawing file.

Displays a Save File dialog window.

  • Select a folder.

  • Type a name in the File Name field.

  • Select either Drawing Exchange Format (*.dxf) or Standard Drawing File (*.dwg) from the Save as type list button.

  • Click the Save button to create the file.

Save 3D geometry

Saves the 3D solid of the unfolded metal part as a separate drawing file.

Displays a Save File dialog window.

  • Select a folder.

  • Type a name in the File Name field.

  • Select either Drawing Exchange Format (*.dxf) or Standard Drawing File (*.dwg) from the Save as type list button.

  • Click the Save button to create the file.

Optimize Bend Annotations

Optimizes the bend annotations in the exported geometry.

Export to Jetcam

Saves the 2D geometry of the unfolded metal part as a separate drawing file.

This option is not available if the SMTARGETCAM system variable is not defined (empty).

Displays a Save File dialog window.

  • Select a folder.

  • Type a name in the File Name field.

  • Select either Drawing Exchange Format (*.dxf) or Standard Drawing File (*.dwg) from the Save as type list button.
    Layer properties use Jetcam standards.
    A <drawing_name>.ppi file, holding unit and material specifications, is generated automatically.

  • Click the Save button to create the files.
