Open BIM is a universal approach to the collaborative design, realization and operation of buildings based on open standards and workflows. This means that Open BIM and even BIM in general is all about processes and not about a software. Still, we need software to enable BIM. 3D modelling and adding information to this model requires dedicated software. For what the engineering market is concerned, the Nemetschek group offers several high performance solutions: Allplan Engineering - general modelling software with a focus on structural detailing for concrete (incl. reinforcement) Scia Engineer - multi-material structural analysis software In the following sections we will go more in depth for each of the above software solutions.
