Link Utilities

Coordinate your analysis and BIM models. This two-way link allows you to transfer seamlessly between Autodesk® Revit®, RISAFloor, RISA-3D and RISAConnection.

Seamless model integration that maximizes your structural design workflow

Simplicity in Model Creation

More and more, structures are becoming exceedingly complex requiring an added level of precision in model creation and management. As a result, RISA promotes a separation of tasks in order to streamline the modeling process with tools catered to exactly what you need to create. Whether you're modeling columns, connections, foundations or entire floor systems, you’ll have confidence that your structure is built properly.

RISA Integration

A Fully Integrated Design Workflow

Whether designing floors, lateral systems, foundations, connections or individual components, your design information and results (model data, member end forces, reactions) from one RISA software can be leveraged in another allowing you to save time, avoid mistakes and maximize coordination.

BIM That Goes Beyond Architecture

Interoperability isn’t just for architects anymore. As engineers, we are being asked to participate in collaborative, model based workflows on a regular basis. That’s why RISA gives you the ability to exchange model information with architectural design packages like ARCHICAD and REVIT, while also improving coordination downstream with detailing software such as SDS/2 and Tekla Structures.
