The Paracore Visual Query Builder

The Visual Query Builder (VQB) is a professional bridge that allows you to build complex Revit model filters with zero code.

1. Interface & Logic​

Accessible via the New Script modal, the VQB allows you to visually assemble queries by adding Categories, Parameters, and specific Rules.

  • Rules Logic: VQB supports nested AND/OR groupings, allowing for highly sophisticated data filtering.
  • Ease of Use: Search and select from every Revit Category and Parameter via intuitive dropdowns.

2. Query Templates​

You don't have to start from scratch. Use existing Query Templates from the gallery as starting points. Select a template, refine the rules to match your project needs, and hit Build.

3. High-Performance Generation​

When you build a query, Paracore automatically generates native C# code using the ElementParameterFilter API.

  • Native Optimization: These queries are faster than manual LINQ filtering because they target the Revit database at the lowest level.
  • Ready for Action: The generated code is immediately functional for both on-demand Scripts and background Sentinels.
