If you are encountering issues with TOH Rebars V1.2.0, the following steps are standard for resolving extension errors in SketchUp: Reinforcement Detailing Plugins for Sketchup - Extensions 17 Aug 2024 —

It sounds like you’re looking for a fix for the TOH Rebars v120 extension in SketchUp (likely a rebar detailing tool, possibly for older SketchUp versions like 2017–2020).

However, I must clarify a few important points:

  1. TOH Rebars is not an official Trimble/SketchUp extension. It appears to be a community or custom plugin (possibly from a forum like SketchUcation or a specific structural engineering group).

    • “v120” may refer to a version number or a compatibility patch for SketchUp 2020/2021 era.

  2. Common issues with such plugins after download:

    • Missing .rbz or incorrect installation.
    • Incompatibility with newer SketchUp versions (2023–2025).
    • Missing dependencies (e.g., TOH Tools, LibFredo6, or older Ruby 2.x requirements).
    • Windows/macOS path issues or antivirus blocking the load.

  3. Possible fixes (general troubleshooting):

    • Install correctly: Extensions Manager → Install Extension → select .rbz (if you have the file).
    • For older .rb files: Place in SketchUp 20XX/Plugins/ folder manually.
    • Check compatibility: The plugin likely works only up to SketchUp 2021 (Ruby 2.7). For newer SketchUp, you may need an updated version or alternative.
    • Enable “Use Legacy Ruby 2.7 API” (if using SketchUp 2024+ with compatibility mode).
    • Error on load: Look for pop-up errors, then open Window → Ruby Console to see missing library names.
    • Antivirus: Sometimes deletes the .rbs or .so files — restore from quarantine.

  4. Where to get a working version (legally & safely):

    • Check SketchUcation Plugin Store (if still listed).
    • Search GitHub for “toh rebars sketchup” — some forks may have fixes.
    • Structural forums like Eng-Tips, SketchUp Community, or Russian/European CAD forums (where “TOH” sometimes appears as “ТОХ Арматура”).

If you have a specific error message (e.g., “undefined method”, “LoadError”), share it here and I can help you patch the code or find a workaround.

Important: I cannot provide a direct download link to a fixed version unless it’s open-source and legally redistributable. But I can guide you to modify the files you already have.

Essay: Fixing the TOH Rebars V120 Extension for SketchUp — Troubleshooting, Causes, and Solutions

The TOH Rebars V120 extension for SketchUp is a specialized plugin used by structural engineers, detailers, and modelers to automate reinforcement placement and generate rebars within SketchUp models. Like all third-party extensions, it can encounter installation, compatibility, or runtime issues that interrupt workflows. This essay outlines common failure modes, diagnostic steps, and practical fixes for getting TOH Rebars V120 working with SketchUp again, concluding with preventative recommendations for a more stable plugin environment.

Common Failure Modes

  • Installation failure: The extension fails to install or is not listed in SketchUp’s Extension Manager.
  • Missing or broken UI: Toolbar buttons, menus, or dialog windows for TOH Rebars don’t appear.
  • Runtime errors: Scripts throw Ruby or runtime exceptions when creating or editing rebars.
  • Incompatibility: Extension version mismatches SketchUp version (e.g., V120 not built for current SketchUp API).
  • Licensing or activation issues: Extension requires activation that fails.
  • Performance and memory issues: Large models cause the extension to hang or crash.
  • File corruption: Extension package or resource files (Ruby files, icons, DLLs) are corrupted.
  • Conflicts with other extensions: Namespace collisions, overwritten UI elements, or shared dependencies cause malfunction.

Root Causes

  • SketchUp API changes: SketchUp’s Ruby API changes between major releases; older extensions may use deprecated methods.
  • Ruby interpreter differences: SketchUp ships different Ruby versions across releases; syntax or library incompatibilities can break code.
  • Incorrect installation path: Manual extraction to wrong folders prevents SketchUp from loading the extension.
  • Permission restrictions: OS file permissions (macOS Gatekeeper, Windows UAC) block plugin files or native libraries.
  • Missing dependencies: The extension expects supporting libraries or native binaries not present on the system.
  • Corrupt download or partial upgrade: Incomplete download or interrupted updates leave inconsistent files.
  • Conflicting extensions: Other plugins overriding methods or adding incompatible hooks.
  • 32-bit vs 64-bit native components mismatch: Native binaries bundled with the extension incompatible with host OS/SketchUp.

Diagnostic Steps (ordered, actionable)

  1. Confirm SketchUp version and Ruby version:
    • Open SketchUp > Help > About SketchUp to note exact version and Ruby version.
  2. Check extension compatibility:
    • Verify TOH Rebars V120 lists compatibility with your SketchUp version (release notes or vendor page).
  3. Restart SketchUp and the machine:
    • Simple restarts often clear temporary locks or resource conflicts.
  4. Inspect Extension Manager:
    • Window > Extension Manager: confirm TOH Rebars is installed and enabled; check for visible errors.
  5. Review Ruby Console:
    • Window > Ruby Console: run a simple operation with TOH Rebars and watch for stack traces or error messages; copy errors for diagnosis.
  6. Reinstall cleanly:
    • Remove existing TOH Rebars files (via Extension Manager or manually), then reinstall from a fresh, verified download.
  7. Verify file integrity:
    • Re-download the extension from an official/known-good source and compare sizes or checksums if available.
  8. Check OS permissions and security:
    • On Windows, run SketchUp as Administrator once; on macOS, check Gatekeeper and allow the app or libraries.
  9. Test in a clean SketchUp profile:
    • Temporarily disable other extensions (one-by-one or all) to isolate conflicts.
  10. Validate dependencies:
  • Ensure any required libraries (e.g., native DLLs, helper gems) are present and compatible (32/64-bit).
  1. Update SketchUp or use compatible version:
  • If API incompatibility is evident, either update the extension (if available) or use a SketchUp version the extension supports.
  1. Contact developer with logs:
  • If errors persist, collect Ruby Console output, SketchUp version info, OS details, and steps to reproduce; send to the extension author.

Practical Fixes

  • Reinstall from official source: Download the latest V120 package from the extension developer’s site or trusted repository and install via Extension Manager (.rbz) for a clean install.
  • Use the correct installation method:
    • SketchUp: Window > Extension Manager > Install Extension and choose the .rbz file. Avoid manual copying unless the developer instructs it.
  • Update or rollback SketchUp:
    • If V120 targets a newer API, update SketchUp; if V120 is older, install a SketchUp release that matches the extension’s supported versions.
  • Apply patches or updated builds:
    • Check the extension’s release notes or support channel for hotfixes specifically addressing V120 issues.
  • Fix Ruby errors by editing scripts (advanced):
    • For known deprecations, patch the offending lines (e.g., replace removed API calls with supported alternatives). Always back up original files before editing.
  • Resolve permission issues:
    • Adjust file/folder permissions so SketchUp can read plugin files; on macOS, permit apps in Security & Privacy settings.
  • Remove conflicting extensions:
    • Disable or uninstall plugins that manipulate the same menus or classes; test TOH Rebars with only it enabled.
  • Replace corrupted resources:
    • Re-download icons, Ruby files, or binaries and replace corrupted ones.
  • Ensure matching native binaries:
    • If V120 ships compiled components, verify they match SketchUp’s architecture (both 64-bit).
  • Use a portable SketchUp profile:
    • Duplicate SketchUp’s configuration to create a clean environment dedicated to TOH Rebars usage.
  • Licensing fixes:
    • Follow vendor activation steps exactly; ensure network access if activation requires it; check firewall or proxy settings.

Example Troubleshooting Walkthrough (concise)

  1. Note SketchUp 2023, Ruby 2.7. If TOH V120 targets Ruby 2.6, expect incompatibilities.
  2. Open Ruby Console, trigger TOH operation, capture stack trace.
  3. Disable all other extensions and retry; if fixed, re-enable extensions in small groups to find the conflict.
  4. Reinstall V120 from vendor, install as .rbz via Extension Manager.
  5. If error persists mentioning a missing method, open the indicated .rb file, search for deprecated API usage, and either patch the line or ask the developer for an updated build.
  6. If crash occurs on large models, split the model or increase system resources; check for known memory leaks in V120.

When to Contact the Developer

  • Unclear stack traces referencing internal module failures.
  • Required license activation or server-side checks failing.
  • Crashes that persist after clean reinstall, OS permission fixes, and disabling other plugins.
  • When source code change is required but not feasible for you.

Prevention and Best Practices

  • Maintain plugin/version matrix: document which extension versions work with which SketchUp releases.
  • Keep backups of SketchUp plugins and user profiles before upgrades.
  • Test plugin updates on a non-critical machine or profile first.
  • Use the Extension Manager to enable/disable plugins when diagnosing issues.
  • Keep SketchUp and critical plugins updated in tandem; check release notes for API changes.
  • Limit installed extensions to those you actively use to reduce conflict surface.
  • Report reproducible bugs with logs and minimal test cases to the developer.

Conclusion Fixing TOH Rebars V120 involves methodical diagnosis—confirming version compatibility, capturing Ruby Console errors, clean reinstall, isolating conflicts, and ensuring dependencies and permissions are correct. For many users, the path to resolution is a fresh install from the official source and running SketchUp with a clean extension set; for API-related failures, either patching the extension code or switching to a compatible SketchUp release is necessary. Persistent or unclear failures should be reported to the developer with log files and system details to obtain an updated, compatible build.
