Depending on the defining project requirements or particular workflows a structural engineering company works to, it may choose for example to start the design process from either a new or existing Revit documentation model or perhaps from an analytical model.
The Autodesk BIM workflow supports both methodologies (and each has its benefits), but for the purpose of this blog post and to demonstrate the workflow we’ll start from an existing documentation model.
In Revit Structure as structural components are placed into the model, an analytical representation is added as well.
Although Revit Structure does not perform actual analysis calculations it can provide all the information required for structural analysis when passed through to Robot Structural Analysis software.
A side benefit of this workflow is of course the ability to use filtered views in Revit Structure to create separate analysis models where these are required.
In addition to basic analytical data you can also create load combinations, by using a formula based on existing loads.
We can also use the Analytical Model Settings tab in the Structural Settings dialog to adjust how Revit performs certain tasks on the analytical model.
We also have the ability to specify family symbols and adjust the spacing for each boundary condition representation.
Another powerful benefit of using this workflow is that we have a bidirectional link with Autodesk Robot Structural Analysis Software, so we can transfer the Revit structural model and perform analysis calculations, and we can then update the Revit model based on the results.
This results in a very efficient and productive workflow.
