Convert Revit Projects to Database with Drawings & Specifications using DDC

Description

Turn a .rvt project into open, analysis-ready data (XLSX + optional DAE/PDF) using the RvtExporter.exe from the DDC Revit toolkit. This n8n template provides a Form UI to set paths and flags, then runs the exporter with safe defaults.

Converts CAD/BIM files with customizable export modes (basic: 309 categories, standard: 724 categories, complete: all 1209 categories) and optional outputs like bounding box, Revit schedules, or PDF drawings.

What it does
Launches RvtExporter.exe with your chosen Revit file and export mode
Optional feature flags: bbox, schedule, sheets2pdf, -no-xlsx, -no-collada
(Optional) Output folder auto-generates _rvt.xlsx and _rvt.dae names

Prerequisites
Windows host (the exporter is a Windows executable)
DDC Revit toolkit installed (path like: C:\\DDC_Converter_Revit\\datadrivenlibs\\RvtExporter.exe)
A local .rvt file you can read

How to use
Import this json workflow into n8n.
Open the Form UI trigger (ensure pop-ups are allowed).
Fill in:
Path to Revit Converter: C:\\DDC_Converter_Revit\\datadrivenlibs\\RvtExporter.exe
Revit File Path: e.g. C:\\Sample_Projects\\your_project.rvt
Export Mode: basic | standard | complete | custom
Conversion Options: multi-select flags (optional)
(optional) output_folder: e.g. C:\\DDC_Output
Click Submit → the workflow runs Run Revit Exporter.
