<!--T:24-->
'Make a linear pattern of features' - This tool takes a set of one or more selected features as its input (the 'originals'), and produces with it a second set of features translated in a given direction. For example:

==Description== <!--T:2-->
===Select a face===
Pressing the button labeled 'Direction' allows to select a face or an edge from a pre-existing solid to specify the direction. The pattern direction will be normal to the face if a face is selected. Note that the button must be pressed again every time to select a new face or edge.


<!--T:4-->
===Select originals===
The {{KEY|[[File:PartDesign_LinearPattern.svg|24px]] '''LinearPattern'''}} tool creates evenly spaced copies of a feature in a linear direction. As of {{VersionPlus|0.17}} the Linear pattern tool can pattern multiple features.
The list view shows the 'originals', the features that are to be patterned. Clicking on any feature will add it to the list.

===Length and Occurrences ===
[[File:PartDesign LinearPattern example.svg|none]]
Specifies the length to be covered by the pattern, and the total number of pattern shapes (including the original feature). For example, six occurrences in a length of 150 would give a spacing of 30 between patterns (150 divided by 5, since there are 5 'gaps' between a total of six occurrences!).

Description

The LinearPattern tool creates evenly spaced copies of a feature in a linear direction. As of version 0.17 and above the Linear pattern tool can pattern multiple features.

Above: An L-shaped pad (B) made on top of a base pad (A, also referred to as support) is used for a linear pattern. The result (C) is shown on the right.

Usage

To create a pattern:

  1. Select the feature (introduced in version 0.19 or several features) to be patterned.
  2. Press the LinearPattern button.
  3. Define the Direction. See Options.
  4. Define the Length (distance) 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 for example the image in the PolarPattern feature. 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.
  7. Press OK.

To add or remove features from an existing pattern:

  1. Press Add feature to add a feature to be patterned. The feature must be visible in the 3D view:
    1. Switch to the Model tree;
    2. Select in the tree the feature to be added and press Space to make it visible in the 3D view;
    3. Switch back to the Tasks panel;
    4. Select the feature in the 3D view; it will be added to the list.
    5. Repeat to add other features.
  2. Press Remove feature to remove a feature from the list, or right-click on the feature in the list and select Remove

Options

LinearPattern parameters in v0.16 and below.
LinearPattern parameters in v0.17 and above.

Direction

When creating a linear pattern feature, the LinearPattern parameters dialogue offers different ways of specifying the pattern direction.

Horizontal sketch axis

Uses the horizontal axis of the sketch for direction.

Vertical sketch axis

Uses the vertical axis of the sketch for direction.

Normal sketch axis

version 0.17 and above Uses the normal axis of the sketch for direction.

Select reference...

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

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

version 0.17 and above Select one of the Body Origin's standard axis (X, Y or Z) as direction.

Limitations

  • Pattern shapes may not overlap one another except for the special case of only two occurrences (original plus one copy)
  • Any pattern shapes that do not overlap the original's support will be excluded. This ensures that a PartDesign feature always consists of a single, connected solid
  • The PartDesign patterns are not yet as optimized as their Draft counterparts. So for a bigger number of instances Draft array is currently the way to go.
  • For further limitations, see the mirrored feature
