Layer state and colour

Every row in the Quick Layer popup (MDQUICKLAYER) carries the same controls you would open the Layer Properties Manager for. Using them does not close the popup, so a run of layer housekeeping happens in one place.

1. 1The filter at the top right lists all layers, only used ones, or only xref layers: click to switch.
2. 2Shift-click to select several rows; a control then changes all of them.
3. 3On or off, freeze, lock and plot, then the colour swatch: one click each.

The controls

Control	What it does
Lightbulb	Turns the layer on or off
Snowflake	Freezes or thaws the layer
Padlock	Locks or unlocks the layer
Printer	Includes the layer in plots, or excludes it
Swatch	Opens the colour dialog built into AutoCAD software for that layer

Editing several layers at once

Shift-select a run of rows (a filtered search result, for instance), and one click applies to all of them, in a single transaction with one regen.

The rule for what “all of them” become is the one the native Layer Manager uses: the clicked row’s resulting state is the target the rest are set to. Click a lit bulb in a mixed selection and they all turn off, rather than each flipping in isolation.

Two details that keep a batch usable:

• Clicking a state button never changes which rows are selected, so the batch survives the toggle and you can keep going.
• If a clicked row isn’t part of the current multi-selection, the click acts on just that row.

What AutoCAD^® software won’t allow

Two edits are refused by AutoCAD software itself, and Quick Layer skips them up front with a plain note at the command line rather than an error, matching what the native Layer Manager does:

• Freezing the current layer.
• Making Defpoints plottable.

More generally, every state change is read back from the drawing after it’s applied. If AutoCAD software rejects an edit, that row’s icon stays as it was instead of showing a state the layer isn’t actually in.
