About

CalcSteel is a web-based structural steel design and analysis platform built to make professional engineering tools affordable and accessible. It features a full 3D browser editor that allows engineers to model structures directly online without downloads or installations. The platform includes a 6 DOF FEM solver and design verification according to major international standards such as AISC 360, Eurocode 3, NBR 8800, AS 4100, and IS 800. With over 640 steel profiles available, users can quickly assign sections and loads to their structural models. CalcSteel enables engineers to analyze, verify, and generate professional documentation and PDF drawings within minutes. Unlike traditional structural software that costs thousands per year, CalcSteel offers a free tier and paid plans starting at accessible monthly pricing. Designed for structural engineers, fabricators, firms, and students, it provides professional-grade tools without enterprise-level costs.

About

SDS2 is an all-in-one steel detailing and connection-design software platform built to help detailers, fabricators, and structural engineers deliver accurate, fabrication-ready steel models and drawings with speed, automation, and integration. It supports modular packages, from basic 2D drafting to full 3D modeling plus shop-drawing generation, enabling users to create precise shop drawings, erection drawings, or full BIM models depending on their needs. SDS2 features automated connection design calibrated to framing conditions and fabrication preferences, intelligent clash detection, and live multi-user modeling so teams can collaborate in real time without conflicting data. It produces high-quality, code-compliant documentation and delivers production-ready output that can feed fabrication equipment or support CNC/automated workflows. SDS2 also interoperates with major BIM and fabrication-management systems via standard file formats.
