RUKN Search — Select by Revit ID

A free Navisworks add-in that locates and selects model elements using their original Revit Element IDs.

Free

RUKN Search is a lightweight, free Navisworks add-in that lets you locate and select model elements using their original Revit Element IDs. Paste single IDs or comma-separated lists and instantly highlight the matching geometry — perfect for coordination, clash resolution, and QA workflows.

Key Features

  • Quick Element Selection
    Locate any Revit element inside Navisworks in seconds.
  • Bulk Selection
    Select multiple elements at once by entering comma-separated IDs (e.g. 102435, 102436, 102440).
  • Validation & UI Feedback
    Built-in verification warns you if a Revit model is not loaded or if an invalid ID is entered.
  • Ribbon Integration
    Adds a dedicated, easy-to-access RUKN Search tab to the Autodesk Navisworks ribbon.

How It Works

Autodesk Navisworks stores original Revit Element IDs within the internal property attributes. This add-in programmatically queries the property LcRevitId (found in the LcOaNat64AttributeValue category) across all elements in the active document and matches them against user input to select them.

Getting Started

  • Open your model
    Load a Revit model (NWC/NWD) in Autodesk Navisworks.
  • Launch the add-in
    Navigate to the RUKN Search tab on the Navisworks ribbon and click RUKN Search — Select by ID.
  • Enter Revit IDs
    Paste a single Revit Element ID or multiple comma-separated IDs into the text box.
  • Select
    Click Select — the corresponding elements are immediately highlighted and selected in your Navisworks workspace.

Installation

Recommended: run the standalone installer RUKN_Search_Setup.exe — a modernized single-page UI that automatically closes any running Navisworks (Roamer.exe) instance before installing to prevent file-lock conflicts. Manual alternative: copy the compiled RUKN.Search.bundle folder into %appdata%\Autodesk\ApplicationPlugins\.

System Requirements

  • Autodesk Navisworks Manage or Simulate 2022–2026
  • Windows 10/11 (64-bit)
