Editing the Sheet Metal Parameters

You can define Sheet Metal parameters to be able to create your first feature.

  1. From the Model section of the action bar, click Sheet Metal Parameters .
  2. To define the standard to use with the 3D shape, click .
    The name of this standard file is defined in a design table.
  3. Optional: In the Thickness box, enter a value.
  4. Optional: In the Bend Radius box, enter a value.
    It corresponds to the internal radius and by default, it is linked to the creation of the bends.
    Important: The inner angle between two elements is used to define the bend. It can vary from 0° to 180° exclusively. This angle is constant and the bend axis is rectilinear.
  5. In the Unfold method area, select the unfold method, and specify its parameters:
    OptionDescription
    K-factorDefines the neutral fiber position inside the thickness, from the inner side of the bend.
    Bend AllowanceThe bend allowance corresponds to the unfolded bend width.
    Bend DeductionThe bend deduction represents the sheet metal deformation when the bend is unfolded.
    Bend Table from StandardsUses the bend deduction table defined in the standards. You must select a standard containing a bend deduction table.

    Notes:
    • The Bend Table from Standards unfold method is automatically selected if a bend deduction table is present in the main sheet metal design table. If you do not want to select this method, you must change to a design table that does not contain a bend deduction table.
    • This functionality is also applicable to features created before R2022x GA after the unfold method is modified for the first time.

  6. To modify the K-factor, use the formula editor or the DIN formula.
  7. In the Bend extremities list, select one of the following:
    OptionDescription
    Minimum with no relief The bend corresponds to the common area of the supporting walls along the bend axis, and shows no relief.
    Square relief The bend corresponds to the common area of the supporting walls along the bend axis, and a square relief is added to the bend extremity. You can modify the Length 1 and the Length 2 parameters if required.
    Round relief The bend corresponds to the common area of the supporting walls along the bend axis, and a round relief is added to the bend extremity. You can modify the Length 1 and the Length 2 parameters if required.
    Linear The unfolded bend is split by two planes going through the corresponding limit points (obtained by projection of the bend axis onto the edges of the supporting walls).
    Tangent The edges of the bend are tangent to the edges of the supporting walls.
    Maximum The bend is calculated between the furthest opposite edges of the supporting walls.
    Closed The bend corresponds to the intersection between the bends of the two supporting walls. The closed bend extremity lies on the surface of the encountered bend.
    Flat joint The two bends are joined in flat view.
