Creating Flanged Holes

You can create flanged holes by specifying punch geometrical parameters.

Before you begin: Create a wall.
  1. From the Refine section of the action bar, click Flanged Hole .
  2. Select the surface.

    A grid appears to help you position the flanged hole.



  3. From the Definition list, select the diameter type.
  4. Specify whether the flanged hole should be created with or without a cone.

    If you clear With cone:

    • The height being automatically computed.
    • The radius value for the flanged hole external curvature must be specified.

  5. Specify whether the flanged hole you be created with or without a burring tap.

    You can use design tables to define a burring tap. It is only available if With cone is selected.

    Notes: If you select With tap:
    • The Radius box is disabled, the radius being automatically computed.
    • The Flat diameter box is disabled and its value is equal to Diameter D or Diameter d depending on the flanged hole type. The diameter value should be similar in both folded and flat views.
    • The support diameter is equal to the minor diameter or the major diameter value depending on the flanged hole type.
    • The support height is equal to height H.
    Warning: If the burring tap is created on non-planar surfaces, you cannot generate an unfolded view in a drawing.
  6. To specify the burring tap, define the thread type and parameters:

    If you select Metric Thick Pitch or Metric Thin Pitch:

    • A Thread Description box lists all available descriptions that use ISO standards.
    • The Pitch value depends on the selected description. The path for the standard files is win_b64\resources\standard\thread\Metric_Thick_Pitch.xml or win_b64\resources\standard\thread\Metric_Thin_Pitch.xml.

    Note: The thread diameter should be greater than the support diameter.
  7. Define the following parameters:
    OptionDescription
    Height Total height

    Use the icon next to the box to specify the reference from which the height is defined: or .

    Radius Radius for the external curvature

    You can click Sketch to edit the positioning sketch.

    Angle Angle

    This option is unavailable with the Two diameters or Punch & die parameters, as the angle is automatically computed in these cases.

    Major diameter Major diameter

    This option is unavailable if you select Minor diameter, as the major diameter is automatically computed.

    Minor diameter Minor diameter

    This option is unavailable if you select Major diameter, as the minor diameter is automatically computed.

  8. Choose the flat pattern diameter:
    OptionDescription
    K-factor Uses the K-factor to compute the diameter.
    Flat diameter Manually defines a diameter value.
    Important: The flat pattern diameter should not exceed the flanged hole external contour.
  9. To create a flanged hole without a fillet, enter clear Use fillet.
