SOFiSTiK Bridge - Infrastructure Modeler 2026

The SOFiSTiK plugin has been developed for infrastructure projects, such as bridges or tunnels. The main purpose of developing the SOFiSTiK plugin is to create parametric 3D bridge models by using the generic families and alignment parameters in the Autodesk Revit software. By using the SOFiSTiK bridge modeller, users are able to create a bridge axis using the alignment parameters.

By using the parameterised bridge profiles of the SOFiSTiK plugin, the bridge components have been modelled along with an axis between the placements. In addition, users are also able to place the substructure element at the placement in the bridge structure. Several additional bridge equipment elements like parapets and railings can also be created by using the SOFiSTiK bridge modeller.

The model achieved by the SOFiSTiK bridge modeller is fully parametric, which has been useful for creating complex bridge structures. In the case of any modifications in the bridge models, the entire model can be updated by using the SOFiSTiK bridge modeller extension. This SOFiSTiK bridge modeller extension helps to support a BIM concept, in which the 3D design model acts as the data source for the planning and construction process.

Discuss the design features of the SOFiSTiK bridge modeller

3D modelling feature

The SOFiSTiK bridge modeller helps to support open, native, big or small BIM design workflows. The SOFiSTiK bridge modeller offers open interfaces, like IFC, SAF, .dwg, .xls and Rhinoceros. The design model created by the SOFiSTiK bridge modeller has been supported by experienced engineers.

Cost-effective feature

The seamless parametrisation feature of the SOFiSTiK bridge modeller extension helps to save time and cost of the design project by providing efficient calculation and structural optimisation features.

Accurate calculation feature

The SOFiSTiK bridge modeller extension also offers more precise mapping of the construction structure history. The innovative technologies of the SOFiSTiK bridge modeller plugin allow the realisation of design structures on the edge of technical feasibility.

Supporting flexible formats for BIM

The SOFiSTiK bridge modeller plugin is flexible for different BIM design workflows, along with open interfaces to the different systems.

Efficient planning feature

The SOFiSTiK bridge modeller plugin also helps to support the entire planning and design process from the creation of the models to the calculation process.

Adaptable feature

The SOFiSTiK bridge modeller plugin is compatible with both independent engineers and global players in the bridge engineering field.

Life-cycle assessment feature

The SOFiSTiK bridge modeller plugin also offers a new life cycle assessment feature, which allows users to estimate the environmental impact of the structural design model. The SOFiSTiK bridge modeller plugin helps to provide default values for concrete and reinforcement steel. By using the SOFiSTiK bridge modeller extension, users are able to compare the results of different variants, and this can be done by exporting these results into one Excel file.

New graphical user interface

The SOFiSTiK bridge modeller plugin helps to offer new graphical tasks for the dynamic moving load train analysis process. In railway bridge designs, the SOFiSTiK bridge modeller plugin can also improve the selection of time step size automatically.

Seismic response spectrum analysis feature

The SOFiSTiK bridge modeller plugin also offers an alternative modelling option, which helps to maintain the rigid diaphragms from COR computation consistently. The refined stiffness modifier feature of the SOFiSTiK bridge modeller plugin helps to provide more flexibility in the engineering process, which helps to resolve the structural behaviours. The extended mode filtering options of the SOFiSTiK bridge modeller plugin also help to support the detection of the relevant modes.

Effectiveness of the SOFiSTiK bridge modeller
