Can I password-protect a DWG file in BricsCAD?

ByCADbrief Staff

Short Answer

No. BricsCAD does not provide a standard PASSWORD command or built-in DWG password protection like some older workflows users expect. The most common professional method is to protect the file outside BricsCAD using a secure ZIP archive or document management system before sharing. This does not encrypt the DWG from inside BricsCAD itself.

What You Need to Know Before

Warning: A DWG marked read-only, locked in Windows, or placed in a restricted folder is not actually password-protected. Many users assume file permissions equal encryption, but anyone with file access can still copy or open the DWG unless you use external encryption.

How to Protect a dwg file in BricsCAD Workflows

  • Command: SAVEAS

  • Shortcut: [Ctrl+Shift+S]

  • Quick Steps:

    1. In BricsCAD, go to the Application menu or Quick Access Toolbar and use Save As to save the final DWG copy you want to distribute.
    2. Close the file, then in Windows Explorer right-click the DWG and add it to a ZIP archive using your compression tool.
    3. In the archive options, enable the encryption option such as Encrypt file names or Set password, then share the protected ZIP instead of the raw DWG.

Variables & Settings

  • Key Setting: In your archive tool, enable the real encryption option such as AES-256 encryption if available instead of basic legacy ZIP encryption, which is weaker and easier to break.

Why it Fails

  • Cause 1 (Geometry): The DWG itself contains all model data normally; saving or purging geometry does not hide sensitive content if the recipient can still open the file.

  • Cause 2 (layers/Locks): Turning layers off, freezing layers, or locking layers does not secure data. Hidden geometry can often still be recovered by someone with CAD access.

  • Cause 3 (Command/Logic): BricsCAD does not offer a native DWG password command, so users looking for in-program protection cannot apply true password security directly during save.

Quick Fix & Best Practice

  • Quick Fix: Use SAVEAS, then place the DWG in an encrypted ZIP with AES-256 protection before sending it.
  • Manager’s Verdict: For real-world project delivery, avoid relying on layer control or read-only attributes. Use encrypted archives, secure cloud sharing, or a document management system when DWG confidentiality matters.

FAQ

Can I set a password when saving a DWG in BricsCAD?

No, BricsCAD does not natively add a password to the DWG during save.

Does read-only protection secure a DWG file?

No, read-only only limits editing behavior and does not encrypt the file.

What is the safest way to share a confidential DWG?

Use an encrypted ZIP archive or a secure document management platform.
