Introduction to Paracore

Paracore is a professional-grade C# automation platform for Autodesk Revit. Born from an architect's passion for the Revit ecosystem, it serves as a high-performance BIM Logic Engine designed to transform complex design automation into high-speed, repeatable workflows.

A New Paradigm in BIM Management​

Paracore V4.1.0 represents a major evolution in Revit automation. It moves beyond simple scripting by providing a Visual Low-Code Environment that generates Revit-native C# logic automatically. It is designed for BIM Managers and Developers who need the power of the Revit API without the traditional barriers of manual code management.

Key Strengths:​

  • Visual Logic Generation: Build complex model filters and data extractions visually. Paracore generates optimized, Revit-native C# code (ElementParameterFilter) that targets elements with near-zero overhead.
  • Active Data Workflows: Manage your model through an interactive Results Table. Edit parameters directly in the grid or use the CSV engine for mass-updates in external tools like Excel.
  • Persistent Template Gallery: Save your best logic as templates. Reuse proven filter graphs across projects to deploy new tools in seconds.
  • Always-On IDE Synchronization: Leverage the full power of VS Code with a real-time (500ms) sync engine. Every save in your IDE is instantly reflected in Revit.
  • Zero-Boilerplate Parameter Engine: Turn C# properties into rich UI controls instantly. Paracore automatically generates dropdowns, sliders, and validation logic without any UI coding.
  • Professional Stability: Engineered for the Windows filesystem, featuring a robust "Safe-Swap" engine that eliminates file locks and ensures reliable script management.

The Three Pillars of Productivity​

Paracore provides three distinct environments tailored to different stages of the BIM automation lifecycle:

1. Script Authoring (Modular Projects)​

Standardize your most complex, repeatable Revit automations. Use Modular Projects to organize C# logic into structured, reusable tools with rich UI metadata and cross-team distribution support.

2. Interactive REPL (BIM Laboratory)​

The REPL is your persistent C# scratchpad for real-time API discovery. Use it to prototype logic, explore model data, and execute one-off commands using Paracore's simplified Extension Methods.

3. Sentinels (BIM Watchdogs)​

Achieve BIM Quality at the Source with background monitoring. Sentinels run continuously, "watching" for compliance breaches and reporting them directly to your secondary monitors for instant resolution.

Active Data Workflow​

Paracore transforms script results into an interactive results table. Edit parameters directly in the grid or use the CSV engine for mass-updates in external tools like Excel.

Architecture at a Glance​

Paracore consists of three primary layers working in harmony:

System Architecture
  1. Paracore Revit Addin: The execution host that lives inside Revit, providing the direct API context and execution engine.
  2. Paracore Desktop App: The modern user interface for script management, parameter configuration, and workflow orchestration.
  3. Backend Sidecar: The local backend service (FastAPI) that manages script discovery, agent logic, and handles communication between the desktop app and the Revit add-in.

Paracore is built for speed, simplicity, and the power of C#. Welcome to a new way of automating Revit.
