What Is a 3D Architectural Walkthrough?
A 3D architectural walkthrough is an interactive, digital experience that lets viewers navigate a proposed or existing space in real time. Built with specialized tools and software, walkthroughs help architects, designers, and clients evaluate layout, materials, lighting, and scale before construction. From fast concept reviews to photoreal marketing, the best tools and services combine high-fidelity rendering, intuitive interfaces, and broad compatibility with CAD/BIM workflows to streamline design iteration and client approvals.
