Draft PolarArray

Description
The Draft PolarArray command creates an array from a selected object by placing copies along a circumference. The command can optionally create a Link array, which is more efficient than a regular array.

The command can be used on 2D objects created with the Draft Workbench or Sketcher Workbench, but also on many 3D objects such as those created with the Part Workbench, PartDesign Workbench or Arch Workbench.



Usage

 * 1) Optionally select one object.
 * 2) There are several ways to invoke the command:
 * 3) * Press the button.
 * 4) * Select the option from the menu.
 * 5) The  task panel opens. See Options for more information.
 * 6) If you have not yet selected an object: select one object.
 * 7) Enter the required parameters in the task panel.
 * 8) To finish the command do one of the following:
 * 9) * Pick a point in the 3D view for the.
 * 10) * Press.
 * 11) * Press the button.

Options

 * Enter the to specify the total angle of the array. The angle is positive in the counter-clockwise direction.
 * Enter the . Must be at least . The maximum that can be entered in the task panel is, but higher values are possible by changing the property of the array.
 * Pick a point in the 3D view, note that this will also finish the command, or type coordinates for the . The rotation axis of the array will pass through this point. It is advisable to move the pointer out of the 3D view before entering coordinates.
 * Press the button to reset the  to the origin.
 * If the checkbox is checked overlapping elements in the array are fused. This does not work for Link arrays.
 * If the checkbox is checked a Link array instead of a regular array is created. A Link array is more efficient because its elements are App Link objects.
 * Press or the  button to abort the command.

Parametric array
To create a parametric polar array use the method  of the Draft module. This method replaces the deprecated method. The method can create Draft OrthoArrays, Draft PolarArrays and Draft CircularArrays. For each array type one or more wrappers are available.

The main method:

The wrapper for polar arrays is:


 * is the object to be arrayed. It can also be the (string) of an object in the current document.
 * is the number of elements in the pattern, including the original object.
 * is the angle of the polar arc in degrees.
 * is the vector that defines the center of the pattern.
 * If is  the created elements are App Links instead of regular copies.
 * is returned with the created array object.

Example:

Non-parametric array
To create a non-parametric polar array use the method of the Draft module. This method returns.
