“Delete layer” dialog
The dialog opens with 🗑 in the “Layers” section for the active layer. Prerequisite: at least a second layer (“At least one layer required”).

Fields
Contents
“Delete layer "…" (no. n). It holds: 5 element(s), 2 hatch(es), 3 dimension(s).” For an empty layer “The layer holds no objects.” is shown and the choice below is omitted.

Move elements to this layer
Default. The list offers all other layers by number; locked ones carry 🔒, hidden ones 👁🗨 — both are allowed as target. Preselected is the active layer, otherwise the first. The objects keep colour, width and line style.
Delete elements together with the layer
Removes the elements of the layer together with its hatches and the constraints. Dimensions go by the same rules as when deleting with Del: if they lie on the layer themselves and in addition if their dimensioned element is deleted with it — even when the dimension lies on the dimension layer. A parallel-distance dimension goes along as soon as its reference line is missing.
Cancel, OK
“OK” executes. If locked or hidden elements, hatches or dimensions lie on the layer, the program asks first: “Careful — layer "…" holds: 2 locked element(s), 3 dimension(s). These objects are moved to layer "…". Continue?” (or “These objects are deleted as well.”). Status bar afterwards: “Layer "…" deleted — n object(s) moved to layer "…"” or “… — n object(s) removed”. One undo step.
What goes with the layer
- If the layer was active, another one becomes active.
- Viewport filters (“Layers in this viewport”) lose the entry.
- If the hatch default layer pointed to it, it switches to the target layer.
- Contents of block definitions are never deleted but re-assigned to the target layer; the instances are rebuilt.
- The change acts in the open space (model or sheet).
