Layer objects on a sheet with the z-order ladder
Learn how each sheet section keeps one z-order ladder, where new objects land, and how to move an object one layer at a time.
Every object in a sheet section (lines, shapes, ellipses, curves, text, images, tables, compass, dynamic schedules, hatchings) shares a single z-order ladder for that section's canvas: indices run 0..N-1 with no gaps.
A newly added or pasted object always gets top position (max+1) - there is no way to insert beneath existing objects except adding then pushing it back.
The object's panel offers '1 Layer Front' and '1 Layer Back' buttons which swap the object one step at a time (indices are re-compacted after every change and after deletes, so the ladder never has holes).
