- Sequential analysis: results from one analysis are used as the initial state for a new analysis
Results
- A wide variety of results in beams and slabs is viewed: deformations, internal forces, supports reactions, connections forces, internal stresses, contact stresses, foundation load table…
- Results are viewed generally for the whole structure or detailed for a selection of elements
- The graphical representation of results is flexible and the user chooses between different possibilities

Output - The document
- The user defines the layout of the document:
- Tables should be printed
- The contents and layout of each table
- “ChapterMaker”, fast creation of pictures and tables
- Customizable front page, headers and footers
- The order: by load case, by element …
- Picture gallery for graphical views
- The document is dynamic: the tables with results are updated automatically when the input data are changed and the structure is recalculated
- Well-structured output is obtained using the automatic paragraph numbering
- The user-defined layouts are stored as a template so that they can be reused for other projects
- “Active Document”: the user may change the project input data in the document.
- The project model will be adapted automatically, the structure is recalculated and the document (results…) will be adapted accordingly
- The document is exported to HTML, ASCII, RTF, PDF, PDF 3D
