Script Execution

Running a script in Paracore is designed to be a safe, predictable, and informative process. Paracore handles the complex tasks of dependency resolution, compilation, and Revit transaction management, allowing you to focus on the results.

How to Run a Script​

  1. Select: Choose a script from the Script Gallery.
  2. Configure: Adjust the values in the Parameters tab of the Script Inspector.
  3. Validate: Ensure there are no red validation warnings (e.g., missing required fields).
  4. Run: Click the Run Script button in the footer of the Inspector.

The Execution Lifecycle​

When you click "Run", Paracore performs the following steps in sequence:

  1. UI Sync: The current parameter values are gathered from the UI.
  2. Project Check: Paracore validates the project structure, ensuring the Scripts/ folder exists and contains exactly one valid entry point.
  3. Compilation: The CoreScript Engine discovers and compiles all .cs files originating from the Scripts/ folder using the Roslyn compiler.
  4. Handshake: The compiled byte-code is sent to the Paracore Revit Addin inside Revit via the Paracore Local Backend (Sidecar) mediator.
  5. Revit Execution: The code runs within the Revit API context. If a Transact block is used, a Revit Transaction is automatically started and committed.
  6. Reporting: Output and status are streamed back to the Paracore Desktop App.

Monitoring Results​

After execution, the Inspector provides several ways to review the outcome:

  • Success/Failure Indicators: A green checkmark (✅) or red cross (❌) appears next to the Run button.
  • Console Output: Every execution displays its standard output followed by a final status message.
  • Success Message: ✅ Code executed successfully | [Day], [Date] | [Time]
  • Failure Message: If a script fails, the errors and the final status line are displayed in Red:
    • [ERROR] Filename.cs(line, col): error CSXXXX: ...
    • ❌ Script failed to [compile/execute] | [Day], [Date] | [Time]

Handling Errors​

If a script fails, use the Console tab to identify the root cause.

  • Compiler Errors: Syntax issues (e.g., a misspelled class name like Referenc).
  • Runtime Exceptions: Revit API errors (e.g., trying to modify an element that is no longer valid).
  • AI Fix: When a failure occurs, use the Explain & Fix button to automatically analyze and resolve the issue.
