PartDesign PolarPattern

Introduction
'Make a polar 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 rotated around a given axis. For example:

Options
When creating a polar pattern feature, the 'polar pattern parameters' dialogue offers two different ways of specifying the pattern rotation axis.

Standard axis
One of the standard axes X, Y or Z can be chosen with the radio buttons. The pattern direction can be reversed by ticking 'Reverse direction'.

Select a face
Pressing the button labeled 'Direction' allows to select an edge from a pre-existing solid to specify the direction. Note that the button must be pressed again every time to select a new edge.

Select originals
The list view shows the 'originals', the features that are to be patterned. Clicking on any feature will add it to the list.

Angle and Occurrences
Specifies the angle to be covered by the pattern, and the total number of pattern shapes (including the original feature). For example, four occurrences in an angle of 180 degrees would give a spacing of 60 degrees between patterns. There is one exception: If the angle is 360 degrees, since first and last occurrence are identical, four occurrences will be spaced 90 degrees apart.
