Advance Steel is a CAD software application for 3D modeling and detailing of steel structures and automatic creation of fabrication drawings, bill of materials and NC files. It was developed by GRAITEC, but is now an Autodesk product.

Based on a 3D model, dimensioned and labeled 2D general arrangement and shop drawings can be automatically created using drawing styles. The drawings are created in separate DWG files; however, they are linked to track changes. Thus, the drawings can be updated after any model modifications and the drawing revision can be managed.

The software has a variety of predefined drawing styles for the creation of general arrangement drawings and shop drawings for single parts and assemblies. A drawing style is a set of rules used to create a detail drawing and defines the elements that are displayed including labeling and dimensioning preferences.

Drawing styles provide the option to automatically create drawings and to modify the layout exactly to user requirements. Drawing styles are used in a similar way to AutoCAD dimension styles, line styles, etc. The predefined drawing styles are different for each installation and country. Custom drawing styles can also be defined.
