Is there a ʼRead-onlyʼ mode when opening files in BricsCAD?

ByCADbrief Staff

Short Answer

Yes — BricsCAD does support a practical read-only workflow when opening files, most commonly by enabling the Read-only option in the file open dialog before using OPEN. This lets you review or inspect a DWG without saving changes over the original. Limitation: it does not prevent someone else from editing another copy.

What You Need to Know Before

Warning: If you open a drawing normally instead of as read-only, BricsCAD can create a write lock on the DWG, which may block other users on shared storage. Also, opening from cloud-synced or network folders can cause lock-file conflicts if sync is delayed.

How to Open a File in Read-Only Mode

  • Command: OPEN

  • Shortcut: Ctrl+O

  • Quick Steps:

    1. Press Ctrl+O or go to the Application menu > Open.
    2. In the Open dialog, select the dwg file you want to review.
    3. Enable the Read-only checkbox or option, then click Open.

This is the fastest and most common professional method for opening a BricsCAD drawing without writing back to the original file.

Variables & Settings

  • Key Setting: Read-only option in the Open dialog

  • Expert Setting: When this option is enabled, BricsCAD opens the drawing without normal write access to the source file. This is useful for checking layouts, plotting, or reviewing xrefs without placing a full editing lock on the DWG.

Why it Fails

  • Cause 1 (Geometry): The drawing may contain unresolved xrefs or missing support paths, so the file opens read-only but still appears incomplete or unusable for review.

  • Cause 2 (layers/Locks): The DWG itself may already be locked by file permissions, a network lock, or Windows read-only attributes, which can confuse users into thinking BricsCAD’s read-only option is malfunctioning.

  • Cause 3 (Command/Logic): If the file is opened by double-clicking in Windows Explorer instead of through OPEN, users may bypass the Open dialog and miss the read-only option entirely.

Quick Fix & Best Practice

  • Quick Fix: Always open shared DWGs from inside BricsCAD with OPEN and manually enable Read-only in the dialog.
  • Manager’s Verdict: Use read-only mode for review, plotting, and coordination on live project files; avoid it when you expect to save layer states, recover data, or update referenced content.

FAQ

Can I edit a drawing opened as read-only?
You can make temporary changes in session, but you cannot save over the original file.

Can I save a read-only drawing under a new name?
Yes, use Save As to create a separate editable copy.
