Is there a ʼLayer Walkʼ tool to quickly check objects on each layer in BricsCAD?

ByCADbrief Staff

Short Answer

Yes — in BricsCAD, the closest professional equivalent to a Layer Walk tool is LAYISO, which lets you isolate objects layer-by-layer for fast visual checking. This is the most common real-world method because it is quick, built-in, and works directly in the drawing. Limitation: it does not provide the exact dialog-based Layer Walk interface found in some other CAD platforms.

What You Need to Know Before

Warning: If your drawing uses nested objects inside blocks or external references, isolating layers may not reveal everything you expect at first glance. Also, if layer isolation settings are configured to lock instead of turn off other layers, users often misread the result.

How to Check Objects on Each Layer in BricsCAD

  • Command: LAYISO

  • Shortcut: No default universal shortcut; type LAYISO

  • Quick Steps:

    1. On the Ribbon, go to Home > Layers panel > click Layer Isolate, or type LAYISO.
    2. Select one or more objects on the layer you want to inspect, then press Enter.
    3. Review only the isolated layer content; when finished, run LAYUNISO to restore the previous layer display.

Variables & Settings

  • System Variable: LAYISOFADECTL (Default: 50)

  • Expert Setting: This controls how much non-isolated layers are faded when the isolation behavior uses fading instead of fully hiding. A higher value makes background layers dimmer, which helps when visually checking crowded drawings.

Why it Fails

  • Cause 1 (Geometry): Objects may be inside blocks, so selecting visible geometry does not always expose all related layer content clearly.
  • Cause 2 (Layers/Locks): Locked, viewport-frozen, or xref-dependent layers can make isolated results appear incomplete.
  • Cause 3 (Command/Logic): LAYISO isolates selected object layers, but it does not cycle automatically through every layer like a dedicated Layer Walk dialog.

Quick Fix & Best Practice

  • Quick Fix: Use LAYISO, then restore with LAYUNISO after each check; if needed, open Layer Explorer to step through layers more systematically.
  • Manager’s Verdict: Use LAYISO for fast production checks in live drawings, but for formal audits across many layers, combine it with Layer Explorer so nothing is missed.

FAQ

Is there an exact Layer Walk command in BricsCAD?
No, BricsCAD typically uses LAYISO and Layer Explorer instead.

How do I bring all layers back after isolation?
Run LAYUNISO.

Can I inspect xref layers with this method?
Yes, but xref layer behavior depends on attachment structure and layer state.
