What this workflow does
This workflow has 16 nodes and runs manually, when you click “Execute workflow”. It uses only n8n's built-in nodes.
How it runs
Trigger: Manually, when you click “Execute workflow”.
- Setup - Define file paths (Edit Fields (Set)): sets 2 fields: path_to_revit_converter, revit_file
- Extract - Run Revit converter (Execute Command): runs a shell command on the n8n host
- Check - Did extraction succeed? (If): checks a condition and branches into true / false
- Error - Show what went wrong (Edit Fields (Set)): sets 2 fields: error_message, error_code
- Success - Create Excel filename (Edit Fields (Set)): sets 1 field: xlsx_filename
- Extract - Read Excel file from disk (Read Binary File): uses Read Binary File
- Extract - Parse Excel to data (Spreadsheet File): reads or writes a spreadsheet file (legacy node)
- On the standard 3D View (If): checks a condition and branches into true / false
- Transform - Filter only OST_Walls (If): checks a condition and branches into true / false
- Non-3D View Elements Output (Edit Fields (Set)): sets 3 fields: message, filtered_count, reason
…plus 5 more steps. See the full node list below.
Before you upgrade to n8n 3.0
3 things in this workflow are removed in n8n 3.0. Fix them before you upgrade:
- Read Binary File in Extract - Read Excel file from disk: replace with Read/Write Files from Disk.
- Function (legacy) in Transform - Group by Type Name & sum Volume, Transform - Generate HTML Report: replace with Code node, mode 'Run Once for All Items'.
- Write Binary File in Load - Save HTML Report: replace with Read/Write Files from Disk.
- Also check Spreadsheet File: Convert to File / Extract from File.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| Read Binary File Extract - Read Excel file from disk | Read/Write Files from Disk |
| Function (legacy) Transform - Group by Type Name & sum Volume, Transform - Generate HTML Report | Code node, mode 'Run Once for All Items' |
| Write Binary File Load - Save HTML Report | Read/Write Files from Disk |
