ISBCAD – Professional Structural Steel Detailing and Fabrication Software for Civil Engineering

ISBCAD is a specialized structural steel detailing software developed by ISB CAD Software, designed to streamline the steel fabrication workflow from concept to production. The software runs on Autodesk AutoCAD and provides a comprehensive environment for modeling steel structures, detailing connections, producing shop drawings, and generating manufacturing data for CNC machines.

The platform supports a wide range of steel structure types including industrial buildings, warehouses, bridges, towers, and mezzanines. It includes extensive libraries of steel profiles and connections, automatic drawing generation, and powerful reporting tools.

Primary Users

ISBCAD is designed for civil engineers, structural steel detailers, fabrication contractors, and steel construction professionals who need a complete solution for steel detailing and fabrication documentation. It serves professionals who:

  • Create detailed 3D models of steel structures including industrial buildings, warehouses, bridges, towers, and steel frames

  • Generate fabrication-ready shop drawings, assembly drawings, and general arrangement drawings automatically from the 3D model

  • Produce accurate bills of materials (BOM), weight calculations, and quantity takeoffs

  • Design steel connections using extensive libraries of standard and custom connection types

  • Generate NC and CNC data for cutting, drilling, and profiling machines
