CATIA V5 Customizing Toolbars and Restoring Lost Commands

CATIA V5 Customizing Toolbars and Restoring Lost Commands

A Reddit user in r/CATIA posted a problem that I've seen dozens of times: they stopped using CATIA for about a year, and when they came back, they couldn't select the Transformation features pattern. They went to Customize, Toolbar, and selected "Restore all contents" — but it didn't fix the issue. This is a surprisingly common problem in CATIA V5, and the solution isn't as obvious as it should be.

Why Toolbars and Commands Disappear

CATIA V5 stores toolbar configurations and command availability in the CATSettings folder. When these files get corrupted — which can happen after a crash, a version update, or even a Windows update — commands and toolbars can disappear with no obvious way to restore them.

Additionally, CATIA's toolbar customization is tied to the workbench you're in. A command that's available in the Part Design workbench may not appear in the Assembly Design workbench. If your workbench defaults got reset, you may be looking for a command in the wrong workbench.

Fix 1: Full CATSettings Reset

This is the nuclear option, but it's the most reliable fix. I recommend trying this first because partial fixes often leave you chasing multiple issues.

1. Close CATIA completely
2. Open your CATSettings folder:
   • Check environment variable CATUserSettingPath
   • Default: %APPDATA%\DassaultSystemes\CATSettings
3. Rename the entire folder to CATSettings_backup_YYYYMMDD
4. Restart CATIA
5. All settings will be reset to defaults — toolbars, commands, standards, everything
6. Reapply your custom settings manually

Important: Don't copy files back from the backup folder one by one — if one file is corrupted, you'll reintroduce the problem. Rebuild your customizations from scratch in the fresh environment.

Fix 2: Restore a Specific Toolbar

If you don't want to reset everything, you can try restoring individual toolbars:

1. In CATIA, go to Tools → Customize
2. Go to the Toolbars tab
3. Select the toolbar that's missing commands
4. Click Restore all contents
5. If the toolbar doesn't appear in the list, click New and create it:
   • Name it (e.g., "Transformation Features")
   • Go to the Commands tab
   • Find the missing command in the appropriate category
   • Drag it onto your new toolbar

Fix 3: Check Workbench-Specific Commands

CATIA V5 organizes commands by workbench. The Transformation features (Pattern, Mirror, Rectangular Pattern, etc.) are in the Part Design workbench. If you're in a different workbench, they won't appear in the Customize dialog.

1. Make sure you're in the correct workbench: Start → Mechanical Design → Part Design
2. Then go to Tools → Customize → Commands
3. The Transformation commands should now be listed

If you're in the correct workbench and still can't find the command, the workbench itself may need to be reset:

1. Tools → Customize → Toolbars
2. Look for the "Part Design" toolbar entries
3. If they're missing, the workbench configuration file is corrupted
4. Proceed to Fix 1 (full CATSettings reset)

Fix 4: Rebuild the Standard.dic File

CATIA uses a file called Standard.dic to define which commands are available. If this file is corrupted, commands can disappear entirely.

1. Close CATIA
2. Find Standard.dic:
   • Usually in CATSysStandardResources directory under your CATIA installation
   • Or in the CATSettingPath directory
3. Rename it to Standard.dic.backup
4. Restart CATIA — it will recreate the file from defaults
5. Check if your missing commands have returned

Building a Clean Custom Workspace

Once you've restored your toolbars, here's how I recommend setting up a clean, efficient workspace:

Create Custom Toolbars for Your Workflow

Don't use the default toolbars — they contain commands you never use and are missing commands you use constantly.

1. Tools → Customize → Toolbars → New
2. Create toolbars organized by workflow phase:
   • "My Sketch Tools" — Line, Spline, Constraint, Quick Dimension, Trim
   • "My Part Tools" — Pad, Pocket, Hole, Edge Fillet, Draft
   • "My Pattern Tools" — Rectangular Pattern, Circular Pattern, User Pattern
   • "My Assembly Tools" — Coincidence, Contact, Offset, Fix Together
3. Add only the commands you use regularly

Save Your Workspace

Once you have your toolbars set up:

1. Tools → Customize → Toolbars
2. Note the names of your custom toolbars
3. The CATSettings folder now contains your configuration
4. Back up the CATSettings folder to a safe location
5. If toolbars disappear again, you can restore from this backup

Share Your Workspace with Your Team

1. Copy your CATSettings folder to a network share
2. On each team member's machine:
   • Close CATIA
   • Delete their CATSettings folder
   • Copy your CATSettings folder to the same location
   • Restart CATIA
3. Each user will now have the same toolbar layout

Note: This also copies all other settings (standards, units, display preferences). If you want to share only toolbars, you'll need to identify the specific settings files — but CATIA doesn't document which files store toolbar configurations, so a full copy is the practical approach.

Common Lost Commands and Their Workbenches

| Command | Workbench | |---------|-----------| | Rectangular Pattern | Part Design | | Circular Pattern | Part Design | | User Pattern | Part Design | | Mirror | Part Design | | Thick Surface | Part Design | | Sew Surface | Part Design | | Replace Face | Part Design | | Split | Part Design / Generative Shape Design | | Trim | Generative Shape Design | | Join | Generative Shape Design | | Untrim | Generative Shape Design | | Offset Surface | Generative Shape Design | | Sweep | Generative Shape Design | | Multi-section Surface | Generative Shape Design |

If a command is missing, first verify you're in the right workbench. Then check Customize. Then reset CATSettings.

Sharing Custom Toolbars Across a Team

When multiple engineers need the same toolbar layout, the most reliable approach is to export and import the entire CATSettings configuration. I maintain a golden CATSettings template on our network share that contains our company-standard toolbars, standards, and display preferences. When a new engineer joins or someone's settings get corrupted, we copy the golden template to their workstation. This ensures everyone starts from the same baseline.

One caveat: the CATSettings folder also contains machine-specific settings like recent file lists and window positions. These don't cause problems when copied between similar workstations, but if the screen resolutions differ, toolbar positions may be off. Users can manually reposition toolbars after the copy without affecting the command availability.

Summary

Lost toolbars and commands in CATIA V5 are almost always caused by CATSettings corruption. The fastest, most reliable fix is a full CATSettings reset — rename the folder, restart CATIA, and rebuild your customizations. Trying to restore individual toolbars through the Customize dialog often doesn't work because the underlying configuration files are corrupted. Save yourself the frustration and do the full reset.
