The Voussoir for Autodesk® Revit® plugin is designed to create stereotomic vaults directly within the BIM environment. Combining advanced geometric logic with principles inspired by traditional masonry construction, the plugin enables users to generate, edit, and export vault systems composed of voussoirs and springers in a fully parametric manner.

The tool integrates seamlessly into the Revit workflow by using preconfigured families (included with the plugin) that are automatically instantiated and organized into model groups to form stereotomic vaults.

Key Features:

Parametric Vault Generation:

Generate stereotomic vaults by selecting two opposite walls. The vault is created using default parameters, and all geometric properties (profile type, height, thickness, and subdivision patterns) can then be fully customized through the Edit functionality.

Native Revit Workflow Integration:

The plugin relies on dedicated voussoir and springer families to ensure geometric consistency and complete compatibility with standard Revit modeling practices.

Export Functionality:

Export the resulting vault geometry to external file formats (OBJ, STL, and others), supporting downstream workflows such as analysis, fabrication, or visualization.

Applications:

Advanced BIM Modeling:

Incorporate parametric stereotomic vaults directly into Revit projects without the need for external modeling tools.

Geometric & Structural Analysis:

Export detailed vault geometry for use in external simulation, optimization, or structural assessment tools.

Digital Fabrication Workflows:

Prepare voussoir models for CNC cutting, 3D printing, documentation, or visualization through supported export formats.

The Voussoir plugin offers an intuitive interface, robust parametric logic, and seamless integration into the Revit ecosystem, enabling AEC professionals to model stereotomic vault systems accurately, efficiently, and fully aligned with BIM standards.

This plugin is part of an ongoing research project exploring digital methods for the study of unbuilt stereotomic architecture. Learn more at https://stbim.arq.up.pt/
