Summary

Arrange objects in a circle using 2 different methods. Can avoid clipping objects at the circle edge, and enable counting of objects in the array. The image shows the circular array used to make holes as part of a larger assembly to hold a circular filter.

Instructions

The method parameter should be set to "complete" or "simple":

method simple uses intersection() of a square array with a cylinder

method complete calculates item positions providing the following benefits:

avoid partial items on the edge of the array
ability to count the number of items

The "complete" option ensures that all array objects fully fit in the defined circle area and are not clipped. The "simple" option permits clipping so that the array makes a perfect circle, but the objects on the edge of the circle are likely to be clipped.
