PartDesign LinearPattern/tr

Tanım
The tool creates evenly spaced copies of a feature in a linear direction. As of 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 ( or several features) to be patterned.
 * 2) Press the  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.  You can change the order by dragging the feature in the list and you will see the result immediately as preview.
 * 7) Press.

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

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
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
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
 * For further limitations, see the mirrored feature
