LayerManager

The LayerManager command opens a table listing every layer in the drawing, with its Freeze, Lock, Plot, Color, Lineweight, and Linetype settings editable directly in the row. It’s the central place to add new layers and adjust how existing ones behave — the other layer commands (LayerMakeCurrent, LayerMatch, LayerIsolate, LayerUnfreezeAll) each do one focused thing without opening it.

Opening the Layer Manager

Type LayerManager in the terminal, or
Click the Layer Manager button in the layer panel.

The dialog opens as a floating panel; nothing needs to be selected first.

The layer table

Column	What it controls
Name	The layer’s name, shown read-only in the table (set once, at creation)
Freeze	Hides the layer’s entities and excludes them from selection until unfrozen
Lock	Prevents entities on the layer from being edited, without hiding them
Plot	Whether the layer’s entities are included when printing or exporting to PDF
Color	The layer’s ACI color — click the swatch to open the color picker
Lineweight	The layer’s line thickness — click the chip to open the lineweight picker
Linetype	The layer’s dash pattern — click the chip to open the linetype picker

Toggling Freeze, Lock, or Plot takes effect immediately — there’s no separate save step. Entities set to ByLayer for color, lineweight, or linetype (the default) pick up whatever you set here; entities with an explicit override of their own are unaffected.

Adding a layer

Click + Add Layer at the bottom of the table.
Type a name and press Enter to confirm, or Escape to cancel.

Layer names may contain letters, numbers, spaces, and _, -, $. A name that’s empty, already in use, or contains any other character is rejected with an inline error, and the row stays open for another try.

New layers start unfrozen, unlocked, plottable, with color 7 (white/black), lineweight Default, and linetype Continuous — the same defaults Import assigns to layer 0 in a blank drawing.

What you can’t do here

There is no delete button — layers are never removed once created, only frozen or left unused. There’s also no indicator in the table for which layer is current; that’s set by picking from the layer panel’s dropdown or by LayerMakeCurrent, not from this dialog.

Keyboard reference

Key	Action
`Enter`	Confirm a new layer’s name (while adding)
