10.5.4.3.2.2.1. Create pattern with same alignment

You want to place a profile rail of a series of borings with the same distance.

Step 1: Set a boring, which is to be used as the pattern for the others.

  1. To do so, create a sketch with the following contour...

  1. ...and define a point as the pattern origin (first the Insert point button and then the Pattern origin button).

  2. Close the sketch.

Step 2: Rotate cut.

Rotate the created contour via Cut rotation .

-> Intermediate result: The hole pattern has been inserted.

Step 3: Define boring series.

  1. Create a sketch, which orients itself to the following profile rail view.

  1. Place the desired insertion point for the boring copies (button Insert point).

[Note] Note

Please do not reenter the point of origin!

Step 4: Create boring series.

  1. Click on the history icon Cut rotation and while holding down the CTRL key, click on Sketch 2.

  2. Then, right-click on one of the marked points. -> The context menu command Create pattern shows up.

  3. Confirm this command.

-> End result: The hole pattern has been inserted.

10.5.4.3.2.2.2. Create rotated pattern

The creation of a rotated pattern corresponds to the method of creating a pattern with equal orientation (see above).

[Note] Note

A round assignment of a boring series can be reached by a pattern with equal orientation. For a rotated pattern the borings are centered on a specific reference point (button Reference point for rotated pattern ).

To clarify a rotated pattern the following is explained step-by-step.

Pattern: round borings

Pattern: round borings

Pattern: angular borings

Pattern: angular borings

Rotated pattern: borings centered on point of origin

Rotated pattern: borings centered on point of origin

10.5.4.3.2.2.2.1. Create pattern with circular orientation

The starting basis for the following commentary is a boring that is to be duplicated 12 times.

  1. Via the button Choose new pattern origin... set the pattern origin on the desired boring.

  2. Via Generate sketch on selected face. set a new sketch for the pattern.

    [Note] Note

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

  3. In this sketch, set the point of origin for the construction of the pattern at the same place as the point of origin in the other sketch is located.

  4. Mark the point.

    --> The copy commands show up.

  5. While holding down the CTRL button, select the button Rotate selection .

    Follow the instructions in the status row:

    • Choose rotation point

    • Choose angle by point

    • Choose rotation angle by point

    --> The dialog window Change parameter opens.

  6. Adjust the values in the input fields Number, Rotation point and Angle of rotation and confirm with OK.

  7. Delete the basis point since otherwise it will be created twice (it can be found as the Pattern origin in the other sketch).

  8. Click on the button Accept changes .

    --> The sketch display is closed.

  9. In the History mark Cut extrude and the sketch, which contains the pattern (in this example Sketch 3) and in the context menu, click Create pattern .

    --> The borings are multiplied according to the pattern.

10.5.4.3.2.2.2.2. Angular borings

In the sketch, delete the circle and replace it with a square.

The bore holes are now arranged in squares and circles (but still equally oriented).

10.5.4.3.2.2.2.3. Arrange borings to points of reference

  1. Open the sketch that contains the pattern.

  2. Insert a point in the middle of the pattern.

  3. Click on the button Reference point for rotated pattern and then on the point.

    --> The point of reference for the rotated pattern is now highlighted in yellow.

  4. Then click on the button Accept changes.

    The borings are now aligned on a point of reference.

10.5.4.3.2.2.2.4. Move point of reference of rotated pattern

For special applications it may be useful to move the point of reference.

  1. Click on Move selection .

  2. Click on the reference point to be moved.

  3. The movement vector is now attached to the cursor.

  4. Select the endpoint of the movement vector.

    --> The window Change parameter opens up.

  5. Adjust the values accordingly.

    The borings are aligned to the new point of reference.

10.5.4.3.2.2.3. Irregular patterns

Taking over patterns into the CAD system may be problematic. In ??? a warning may be issued for certain cases.

[Note] Note

The following cases must be differentiated between:

  • Pattern is neither circular (see rotation pattern), nor linear (see linear pattern)

    --> During project tests, a warning always shows up.

  • Pattern is circular or linear + contains less than 25 elements

    --> The number of "empty spaces" is irrelevant.

  • Pattern is circular or linear + contains more than 25 elements

    --> Max. 10% of the spaces my be empty.

Examples:

Linear pattern with 13*2=26 elements with 2 empty spaces Linear pattern with13*2=26 elements with 8 empty spaces Linear pattern with 6*2=12 elements with 7 empty spaces
OK Warning OK
