7.6.2.10.2.2. Create rotated pattern

In rotated patterns the borings are circularly arranged around a central point.

The following example shows the design process of a rotated pattern step by step in detail.

Initial situation: The original hole has already been created using Cut extrude (Sketch 2). This is to be duplicated in a circular shape so that a total of 12 holes are created.

  1. Open the sketch with the original hole and set the pattern origin to the hole using the Pattern origin button.

  2. Use Create new sketch on selected area [Generate sketch on selected face] to create a new sketch for the pattern.

    [Note]Note

    Set the sketch for the pattern points on the same plane as the sketch with the pattern origin.

  3. In this sketch, set the starting point ( Insert Point [Insert point] ) for the construction of the pattern exactly at the same location as the origin point in the other sketch.

  4. Select the point.

    -> In this way the copy commands become enabled.

  5. Hold down the Ctrl key and click the Rotate selection button.

    [Note]Note

    Without Ctrl key is moved, with copied.

    Press the Ctrl key during performing the following steps.

    Follow the notes in status line:

    • Choose rotation point

    • Choose reference angle by point

    • Choose rotation angle by point

    -> The Change parameters [Change parameter] dialog box opens.

  6. Adjust the values in the input fields for Quantity [Amount] (only the number of newly added items), Pivot Point [Rotation point], and Rotation Angle [Rotation angle], and confirm by clicking OK.

  7. Delete the base point using Delete element as it would otherwise be created twice. The base point is located in the other sketch.

  8. Click on the Apply changes [Accept changes] button.

    -> The sketcher is closed.

  9. In the 3D history [3D History], select the Cut extrude construction steps and the sketch that contains the pattern (in the example, sketch 3 ) and click Create pattern in the context menu.

    -> The borings are copied according to the pattern.

  10. Align borings to reference point

    [Note]Note

    A central reference point of the pattern has to be set, because CAD systems won't recognize the pattern as a rotated pattern otherwise.

    • In center of pattern, add a point.

    • Click on the Reference point for rotation pattern [Reference point for rotated pattern] button.

    • Finally, click on the Apply changes [Accept changes] button.

    [Note]Note

    If you follow the same example using a rectangular cutout, you can see how it is aligned with the central reference point .

    The individual elements of the pattern are aligned with the central point .
