Autodesk Advance Steel is an advanced program for creating detailed documentation of steel structures. The AutoCAD working environment, clear interface and advanced tools allow you to quickly build a three-dimensional model, ensuring full control over the designed structure at various stages of its implementation - from initial calculations to assembly at the construction site. This model is characterized by great detail, from various processing of sections and sheets to advanced connection macros with connectors, welds and edges of elements prepared for welding. Creating design documentation based on a three-dimensional model in Advance Steel significantly improves its accuracy, shortens its development time and enables work in BIM. The program's advanced tools significantly improve structure detailing and enable the creation of clear documentation tailored to specific requirements. Documentation in the form of drawings, bills of materials and numerical files is automatically updated.
