Draft PolarArray

Description
The tool creates an array from a selected object placing the copies along a circumference.

This tool can be used on any object that has a Part TopoShape, meaning 2D shapes created with the Draft Workbench, but also 3D solids created with other workbenches, for example, Part, PartDesign, or Arch. It can also create App Links instead of simple copies.


 * To create orthogonal or circular arrays, use the corresponding and  tools.
 * To position copies along a path use or.
 * To position copies at specified points use or.
 * To create copies and manually place them use or.
 * To create exact copies and manually place or scale them, use or.



Usage

 * 1) Select the object that you wish to array.
 * 2) Press the  button. If no object is selected, you will be invited to select one before proceeding.
 * 3) The task panel is launched where you can select the polar angle, the number of elements, and the center of the axis of rotation.
 * 4) You can click on the 3D view to simultaneously set the position of the center of rotation, and complete the command. Otherwise, just press  or the  button to complete the operation.

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 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.
