In path arrays, items are evenly distributed along a path or a portion of a path.
A path can be a line, polyline, 3D polyline, spline, helix, arc, circle, or ellipse.
The distribution of items along the path can be measured or divided.
The Path Array context menu offers a full range of settings for making adjustments to the spacing, number of items, and levels in the array.
You can also use the grips on a selected path array to change the array configuration.
When you hover over the square base grip, a menu of options provides choices. For example, you can select Row Count, and then drag to add more rows to the array.
If you drag the triangular grip, you can change the number of items arrayed along the path.
