Section Box is a Blender add-on for generating architectural and product cross sections. It provides tools to instantiate section boxes around specific objects or collections, enabling users to reveal internal structures and interior spaces. The add-on features dynamic gizmos for spatial control and offers multiple processing methods optimized for different priorities, such as visual fidelity or viewport performance.

Users can save specific cross-section states as custom views for quick retrieval during the design process. The tool also supports one-click exports of the generated sections to the DXF format. Additionally, all settings within the add-on are fully keyframable, allowing for animated cross-section sequences in presentations.
