Section Toolbox is a Blender add-on providing parametric section box controls and planar cut functionality for architectural documentation. This utility streamlines the creation of section cuts within the Blender environment. It provides a set of tools to define section planes and bounding boxes, allowing users to slice through complex 3D geometry dynamically. The interface enables precise alignment and adjustment of these cuts, facilitating the generation of clean, two-dimensional projections from three-dimensional models. By automating the extraction of geometry along defined planes, the tool assists in maintaining consistent scale and orientation across various architectural perspectives, ensuring that the resulting cut representations are accurate and ready for further refinement or documentation workflows.

Users install the script within the Blender preferences menu to integrate the functionality directly into the viewport sidebar. Once active, the tool allows for the definition of cutting planes through object manipulation or numerical input. After setting the desired section, the plugin processes the geometry to generate vector-based data, which can then be exported as SVG or DXF files for use in external CAD or illustration software, bridging the gap between 3D modelling and 2D drafting.

This add-on is essential for architects and visualisers who use Blender for both design development and technical documentation. It is particularly effective during the schematic design and design development phases when rapid iteration of building sections is required. By facilitating the transition from 3D model to 2D line work, it supports the creation of site plans, building elevations, and detailed section drawings. It pairs well with architectural modelling workflows that require precise, scalable output for permit sets, presentations, or construction documentation.
