Can I make a polar array?
No this addon currently only distributes in an orthogonal grid.
Can I distribute a single object and have the addon duplicate it?
No, this isn't the goal of this addon, there are other third party
addons dedicated to arraying a specific element by duplicating it or
copying.The goal of this addon is to distribute a selection of
different specific objects already placed in your scene, like linked
libraries, or populating scenes with assets
How do I stack objects vertically or along the Y axis?
The addon by default works by distributing along X then Y then Z axis by this specific order. If you only want to distribute along the Y axis you can do so by limiting the count on the X axis to 1, so it wraps immediately and starts stacking along Y then Z instead.If you want to stack on Z axis limit both X and Y to the count of 1.
