A building section drawing is a vertical cut-through representation of a building that shows the internal relationships between spaces, materials, and systems. It illustrates how floors, walls, roofs, and foundations connect vertically, providing critical information that complements floor plans and elevations.
Sections help visualize:
Building section drawings can be simple conceptual cuts or detailed technical illustrations used in construction documentation and coordination.
A well-developed building section drawing is essential to:
Sections bridge the gap between spatial design and technical execution—essential in both conceptual phases and construction documentation.
In a mixed-use midrise building, the building section shows how residential floors stack above a commercial base, how floor slabs connect to the façade system, and how elevator shafts rise through all levels. Coordination of fire separation, sound insulation, and MEP penetration zones is resolved within the section drawing before construction begins.
A building section drawing is like slicing a cake down the middle—you see everything inside: the layers, connections, and how the whole thing holds together.
The D.TO platform improves the accuracy and completeness of building section logic by verifying how components connect vertically across modules and assemblies. D.TO evaluates transitions between structural systems and envelope conditions.
By structuring envelope logic with inner/outer modules and phased layers, D.TO helps automate the documentation of conditions typically shown in section views. This enables data-backed detailing that reflects constructible outcomes without manual redlining or rework.
