Fusion is a great plugin to have even more complex array systems than the 3dsmax build in array.
Allow for way more customizations when you array objects over splines. On the new version 0.8.178 you can create more complex geometry by linking objects together with various conditions.
Additionally, you can fasten objects together, distribute, or stretch between other objects or vertices/corners on the spline.
