Feature Pattern on a Cylinder Face

Starting point

The feature to be patterned is modeled on a cylinder or cone surface.

The Ribbon Bar Function

  1. On the tab, in the Tools group, click Pattern.
  2. Select the surface from the feature, from which you create the pattern.
  3. Define the feature pattern properties in the dialog box. Feature Pattern Data
    • Note that Polar is selected.
    • If you want the pattern to have more than one circle, enter:
      • The number in the length direction and
      • The Delta of the circles or the distance between the furthest circles (=Length) in the length direction.
    • Enter the number of pattern members on the circle.
    • Enter the angle or length of the pattern members on the circle.
      • Angle: 360= the pattern is positioned evenly around the cylinder, 180= the pattern is positioned on the half of the cylinder.
      • Delta is the angle between two features on the cylinder face.
  4. Confirm the data in the dialog box by clicking OK.
  5. If you specified more than one as the number in length direction, place the auxiliary geometry sketch that controls the feature.
    • This allows you to determine which direction the other circles come in relation to the original feature.
  6. Select the contextual OK

The Context-Sensitive Function

This function allows you to select multiple features at once and create a pattern of them all.
  1. Select the parent feature from a part as follows:
    • Select one or mode Boss or Cutout operation from the part's feature tree.
    • In addition to these, you can choose a rounding or bevel that is connected to the above selected features.
    • Select on or more face from the part. Select more than one feature by holding down the Ctrl key while clicking with the left mouse button.
    • If you want to create a feature pattern from a rounding or a bevel, you must also include the feature to whose geometry the rounding/bevel has been added.
  2. Select the context-sensitive function Feature Pattern.
  3. Steps 3 … 6, as above.

Example of a single-circle polar pattern

  • Length direction, number: 1.
  • The Length value in the length direction is irrelevant, because there will only be 1 circle.
  • The number of pattern members on the circle: 12.
  • The angle is 360, i.e. the features are added on the entire cylinder surface.

Example of a multi-circle pattern

  • Length direction, number: 3.
  • The distance between the circles is given to the Delta value in the length direction.
  • The auxiliary geometry of the pattern is so positioned that it directs the circles upwards (middle image).
  • The number of pattern members on the circle: 12.
  • The angle is 360, i.e. the features are added on the entire cylinder surface.

Example of a pattern set only on part of the circle

  • Length direction, number: 1.
  • The Length value in the length direction is irrelevant, because there will only be 1 circle.
  • Direction: Counterclockwise
  • The number of pattern members on the circle: 3.
  • Angle: 40 (distance between the most extreme members of the pattern).
