Popis

Tento nástroj vezme skupinu jednoho nebo více objektů (originály) a vytvoří z nich druhou skupinu objektů pootočenou kolem dané osy.

PartDesign PolarPattern example.png

Above: 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.

Použití

To create a pattern

  1. (Optional) Select the feature (introduced in version 0.19 or several features) to be patterned.
  2. Press the PartDesign PolarPattern.svg 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.

Polarpattern parameters.png

Axis

Při vytvoření polárních vzorků nabízí doalogové okno 'parametry polarního vzoru' dva odlišné způsoby specifikování rotační osy.

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

v0.17 and above 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.

Úhel a výskyty

Určuje úhel, který má být vzorky pokryt a celkový počet vzorků (včetně originálního). Například čtyři výskyty v úhlu 180 stupňů dá 60 stupnů mezi vzorky. Je zde jedna výjimka: Je-li úhel 360, protože první a poslední výskyt je identický, čtyři výskyty budou po 90 stupních.
