What this workflow does
This workflow has 26 nodes and runs on a schedule (every day) (plus 1 other trigger). It uses only n8n's built-in nodes.
How it runs
Trigger: On a schedule (every day) (plus 1 other trigger).
- Capture Pipeline Start Time (Code): runs custom JavaScript code
- Set Configuration Parameters (Edit Fields (Set)): sets 6 fields: converter_path, source_folder, output_folder…
- Merge: merges the data from its input branches
- Find CAD Files (Execute Command): runs a shell command on the n8n host
- Merge: merges the data from its input branches
- Process File List (Code): runs custom JavaScript code
- Check if Files Exist (If): checks a condition and branches into true / false
- Split Files for Processing (Split Out): splits a list into separate items
- No Files Found Response (Edit Fields (Set)): sets 2 fields: message, details
- Create Output Directory (Execute Command): runs a shell command on the n8n host
…plus 14 more steps. See the full node list below.
Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- Write Binary File in Save HTML File1: replace with Read/Write Files from Disk.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| Write Binary File Save HTML File1 | Read/Write Files from Disk |
