Tekla Structures is a BIM software solution providing new capabilities for an easy and accurate design of an intelligent model structure. It encompasses the entire process of structural engineering. For the last few decades one has been able to observe the development of IT techniques designed for structural engineering industry. The 70s introduced CAD that is the computer technology of 2D drawing. However, the requirements of modern, often complex projects have shown imperfections of such solutions. As a consequence, it has been increasingly common for the companies to use virtual solutions provided by BIM (Building Information Modelling).
