Built for fast, practical section analysis
XSection gives structural engineers a modern workspace for modelling reinforced concrete sections, checking capacity, reviewing interaction diagrams and generating professional calculation reports - all from a single platform
XSection — Untitled SectionPowerful analysis. Simple to use.
Fast section setup
Create rectangular, circular, wall, pile, pier and custom sections in seconds with an intuitive workspace.
Capacity checks
Check axial, uniaxial, biaxial and interaction capacities with governing results and strain profiles.
Cloud-based
Access your projects anywhere with nothing to install, update or maintain.
Interaction diagrams
Generate N–M, M–M and biaxial interaction diagrams with smooth, high-resolution results.
Professional reports
Generate clear calculation reports with inputs, assumptions, diagrams, governing results and design summaries ready for review or client submission.
Built by engineers
Designed by practising structural engineers to support real-world design workflows.
All-in-one workspace
Model, analyse and document your sections in one place — without spreadsheets or desktop software.
Analysis insights
View strain profiles, force resultants, neutral axis positions and governing failure modes with clarity.
