CalcTree

CalcTree is a cloud-based platform designed to streamline engineering calculations and automate complex computational workflows. The platform enables engineers to define calculations using native MathJS expressions, datasets, embedded Python scripts, or spreadsheets—all within a structured, formula-based editor. CalcTree features real-time collaboration, parameter linking across projects, and a comprehensive calculation template library (both public and private). The platform integrates seamlessly with popular AEC tools through plugins for Excel, Grasshopper, and ETABS, allowing calculations to be embedded in existing workflows. For advanced users, a powerful GraphQL API enables programmatic building and modification of content. CalcTree supports structural design (beam analysis, column design, foundation calculations), mechanical engineering (stress analysis, modal analysis, fatigue estimation), and infrastructure projects. The platform replaces rigid desktop tools with cloud-based flexibility, enabling teams to collaborate across locations and time zones while maintaining IP security through private templates and repositories.
