It is designed for the modeling, nesting, and machining of metal profiles such as I, U, L, and T beams, as well as square and round tubes. The system manages cutting, marking, drilling, and threading operations, with automatic CNC code generation, interactive simulation, and collision detection. It improves material utilization and integrates with ERP and MES systems, ensuring full traceability across industrial production environments.

Up to 20%


Reduce material waste by up to 20% through optimized 3D nesting

Intuitive


Accurate simulation of cutting heads and toolpaths with collision correction

Efficient


Supports standardized profiles and custom geometries

3D CAD design for structural profiles


Lantek Flex3D Steelwork allows users to design, import, or modify profiles such as I, U, L, T beams, tubes, and other standardized sections. Profiles can be fully parameterized, enabling fast adjustments without reworking the design.

Interactive simulation of the complete cutting process


The graphical environment provides a detailed view of cutting paths, head movements, and working areas. The interactive simulation allows users to move forward or backward step by step to validate each phase before generating the final CNC code.

Automatic nesting and scrap management


The system organizes parts on bars and profiles, adjusting cuts to reduce waste. Scrap reuse is handled automatically and considered in future production orders.
