Description

The PartDesign PolarPattern tool creates a polar pattern of one or more features.

A slot-shaped pocket (B) made on top of a base solid (A, also referred to as support) is used for a polar pattern. The result (C) is shown on the right.

Usage

To create a pattern

  1. (Optional) Select the feature (or introduced in version 0.19 several features) to be patterned.
  2. Press the PolarPattern button.
    • If you didn't initially select any features, you'll be able to select a single base feature
  3. Define the Axis. See Options.
  4. Define the Angle between the last copied occurrence and the original feature.
  5. Set the number of Occurrences.
  6. If you have several features in the pattern, their order can be important, see the image below.
  7. Press OK.

Ordering features

Effect of the feature order

introduced in version 0.19 You can change the order by dragging the feature in the list and you will see the result immediately as preview.

Adding features

  1. Press Add feature to add a feature to be patterned.
  2. Switch to the Model tree;
  3. Select in the tree the feature to be added.
  4. Repeat to add other features.

Removing features

  • Right-click on the feature in the list and select Remove.

or

  1. Press Remove feature to remove a feature from the list.
  2. Switch to the Model tree;
  3. Select in the tree the feature to be removed.
  4. Repeat to remove other features.

Options

Axis

When creating a polar pattern feature, the PolarPattern parameters dialogue offers different ways of specifying the pattern rotation axis.

Normal sketch axis

An axis being normal to the sketch and starting in the origin of the sketch of the feature being used is taken as axis for the polar pattern.
The pattern direction can be reversed by ticking 'Reverse direction'.

Horizontal sketch axis

Uses the horizontal axis of the sketch for axis.

Vertical sketch axis

Uses the vertical axis of the sketch for axis.

Custom Sketch Axis

If the sketch which defines the feature to be patterned also contains a construction line (or lines), then the drop down list will contain one custom sketch axis for each construction line. The first construction line will be labelled Sketch axis 0.

Base (X/Y/Z) axis

Select one of the Body Origin's standard axis (X, Y or Z) as axis.

Select reference...

Allows you to select either a DatumLine or an edge of an object or a line of a sketch to use for axis.

Angle and Occurrences

Specifies the angle to be covered by the pattern, and the total number of pattern shapes (including the original feature). For example, four occurrences in an angle of 180 degrees would give a spacing of 60 degrees between patterns. There is one exception: If the angle is 360 degrees, since first and last occurrence are identical, four occurrences will be spaced 90 degrees apart.
