How to undo a mistake and go back to a previous step in BricsCAD?

ByCADbrief Staff

Short Answer

Yes — in BricsCAD, the fastest and most common way to undo a mistake and go back to a previous step is to use the UNDO command, usually with Ctrl+Z. This reverses your last action immediately and is the standard professional recovery method. Limitation: some actions may be grouped into a single undo step.

What You Need to Know Before

Warning: BricsCAD undo behavior depends on how commands were recorded in the current session. If you made many edits inside one command or after certain scripted operations, one undo may remove more changes than you expected.

How to Undo a Previous Step in BricsCAD

  • Command: UNDO

  • Shortcut: Ctrl+Z

  • Quick Steps:

    1. In the drawing area, press Ctrl+Z or type UNDO in the command line and press Enter.
    2. If using the command line method, choose the default undo action to reverse the last operation.
    3. Repeat Ctrl+Z as needed to go back multiple steps; you can also use the Quick Access toolbar Undo button if visible.

  • Use the standard single-step undo method for the fastest workflow.

  • Real setting/option: in the UNDO command, the Control option lets you manage how undo behavior is recorded in the session.

Variables & Settings

  • Key Setting: Undo button on the Quick Access Toolbar

  • Expert Setting: If the Quick Access Toolbar is visible, the Undo button gives a fast visual way to step backward without typing commands. This is useful in production drafting, but keyboard Ctrl+Z is still faster for most professionals.

Why it Fails

  • Cause 1 (Geometry): A complex edit done inside one command may be stored as a single undo group, so one undo removes the whole operation instead of one small change.

  • Cause 2 (layers/Locks): If your “mistake” involved objects on locked layers, the command may not have changed them at all, making it seem like undo is not restoring the expected result.

  • Cause 3 (Command/Logic): After save, script-driven edits, or certain command sequences, the undo history may not match your mental workflow, so stepping back can feel inconsistent.

Quick Fix & Best Practice

  • Quick Fix: Press Ctrl+Z once, then check the command line to confirm what was reversed; if needed, use REDO immediately to restore the last undone action.
  • Manager’s Verdict: Use UNDO for normal drafting corrections, but do not rely on long undo chains as a workflow strategy—save versions before major edits, imports, or batch operations.
