What is a ʼLayer Stateʼ in BricsCAD?

ByCADbrief Staff

Short Answer

A layer state in BricsCAD is a saved snapshot of layer properties like On/Off, Freeze, Lock, color, linetype, and plot status, so you can quickly restore a known layer setup using LAYERSTATE. It is the most common professional way to switch between drafting, plotting, and review views. Limitation: it does not fix missing or renamed layers automatically.

What You Need to Know Before

Warning: Restoring a Layer State can overwrite your current layer visibility and lock settings across the drawing. A common failure is applying an old state after layers were added, renamed, or changed in xrefs, which can leave the display incomplete or inconsistent.

How to Restore or Save a Layer State in BricsCAD

  • Command: LAYERSTATE

  • Shortcut: LA

  • Quick Steps:

    1. Open the Ribbon > Home > Layers panel > layer states, or type LAYERSTATE.
    2. In the Layer States Manager, click New to save the current layer setup, or select an existing state to restore.
    3. Choose the layer properties to include, then use Restore. Enable the relevant property options such as On/Off, Freeze/Thaw, Lock/Unlock, or Plot as needed.

Variables & Settings

  • Key Setting: In the Layer States Manager, choose which properties are saved with the state

  • Expert Setting: If you save only visibility-related properties like On/Off and Freeze, the state is safer for presentation switching. If you also include color, linetype, lineweight, and plot status, restoring the state can override standards changes made later in production.

Why it Fails

  • Cause 1 (Geometry): Objects may seem to disappear after restoring a Layer State because their layers are frozen or turned off in the restored configuration, especially in viewport-specific setups.

  • Cause 2 (Layers/Locks): If layers were renamed, deleted, or come from updated xrefs, the saved Layer State may not match the current layer structure.

  • Cause 3 (Command/Logic): A Layer State only restores the properties that were captured when it was created; if a needed option was not saved, restoring the state will not affect that property.

Quick Fix & Best Practice

  • Quick Fix: Run LAYERSTATE, edit or recreate the state, and make sure the required properties like Freeze, Lock, and Plot are included before restoring it again.

  • Manager’s Verdict: Use Layer States for repeatable view control, plotting setups, and discipline-based layer visibility. Avoid relying on very old saved states in fast-changing project files unless they are maintained as part of your CAD standards.

FAQ

Can a Layer State save locked layers?
Yes, if the Lock property was included when the state was saved.

Does a Layer State work with xref layers?
Yes, but results depend on whether those xref layer names still exist and match.

Can I use Layer States for plotting views?
Yes, they are commonly used to switch between work, review, and plot layer setups.
