Disseminating Geometric Figures for Architecture Education and Research Through a Direct Data Stream Between CAD

This article investigates the dissemination of geometric figures for education and academic research in architecture. When extracting 3D geometry and metadata from digital models created using computer-aided design (CAD) software, traditional interoperability workflows based on file exchange often introduce lossy conversions to standardized data schemas. This paper proposes an alternative approach based on a direct data stream between CAD software and a web-based visualization environment, using the open-source collaborative platform Speckle. After outlining the objectives and methods, a state-of-the-art review highlights key technical challenges. A case study based on geometric figures modeled in TopSolid is then presented, involving two development layers: (1) a Speckle connector implemented as a plug-in within TopSolid, and (2) a customized web viewer built using speckle-viewer and Three.js. The results show that a CAD environment can be effectively replicated on the web, enabling flexible and open dissemination of academic content in architectural geometry.
