Batch Convert CAD/BIM Files to XLSX
Batch converts CAD/BIM files from a folder into XLSX/DAE using RvtExporter, verifies the outputs, and opens an HTML summary report.
What it does
Scans a specified source folder for CAD/BIM files such as .rvt, .ifc, .dwg, or .dgn. It runs the local RvtExporter executable to batch convert these files into analysis-ready XLSX and optional DAE formats with configurable export modes. The agent verifies output file existence and size, then generates an automatic HTML summary report upon completion.
Step by step
- The workflow begins with an n8n manual trigger to initiate the batch process.
- A code node executes PowerShell commands that invoke the local RvtExporter executable on target files.
- Post-execution logic checks for the existence and file size of generated XLSX outputs to verify success.
- An HTML summary report is generated using static templates populated with the verification results.
Where the LLM does the work
- Generate robust PowerShell error handling logic that distinguishes between partial failures and total export crashes.
- Create dynamic HTML styling for the summary report to ensure readability across different email clients or browsers.
- Draft configurable parameter strings for RvtExporter modes so users can easily swap between standard and advanced exports.
Watch out for
File locks from open CAD applications can prevent conversion, so ensure all source files are closed or use read-only access flags.
Path length limits on Windows may truncate output paths, so validate that the destination folder path stays under 260 characters.
Large batches can exhaust memory during HTML generation, so stream report data instead of loading entire file lists into RAM.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Batch Convert CAD/BIM Files to XLSX: Batch converts CAD/BIM files from a folder into XLSX/DAE using RvtExporter, verifies the outputs, and opens an HTML summary report. ## Specification - What it does: Scans a specified source folder for CAD/BIM files such as .rvt, .ifc, .dwg, or .dgn. It runs the local RvtExporter executable to batch convert these files into analysis-ready XLSX and optional DAE formats with configurable export modes. The agent verifies output file existence and size, then generates an automatic HTML summary report upon completion. - Trigger: Run manually (Manual · on demand) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - n8n: Workflow orchestration and trigger management - Code: Executing conversion logic via PowerShell and RvtExporter ## Known pitfalls, handle each one explicitly in your implementation 1. File locks from open CAD applications can prevent conversion, so ensure all source files are closed or use read-only access flags. 2. Path length limits on Windows may truncate output paths, so validate that the destination folder path stays under 260 characters. 3. Large batches can exhaust memory during HTML generation, so stream report data instead of loading entire file lists into RAM. ## Reference implementation https://n8n.io/workflows/7650 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Automation Platform than n8n?
Yes. n8n is only the example automation platform in this recipe. The same flow works with Home Assistant. Swap the automation platform connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for developers who want the busywork around code automated, not the code itself.
