Linear array
Select the body, set the count and the direction above, the spacing at the geometry, watch the preview, press Enter.

An array is one feature
All copies live in a single timeline node. So the count and the spacing are edited in one place, and deleting the array removes every copy at once, leaving no litter.
What is set
- Count — how many in total, including the original.
- Direction — along which axis or which edge.
- Spacing — the distance between neighbouring copies; it takes a formula.
A hint
It is convenient to tie the spacing to a global parameter: pitch. Then rearranging the holes on a
plate is a change to one number rather than a rebuild of the array.
