In the past, setting up the Revit analytical model was quite complicated. Autodesk has simplified the process and the analytical elements.
The first thing that might confuse you is that there is no embedded structural analytical element in structural elements. You now need to create the analytical element for yourself.
You can do so manually for columns and beams using the members tools on the analyze tab. You can use the grid display property of the view to help you place the analytical element. The transparency has been set to 50%.
It is sometimes the case that the manual tools will not let you for the necessary association wit the physical element.
In that case, delete the analytical element and use the Analytical Automation tool instead. I prefer using the analytical automation tool by default anyway and reserve the manual creation for special cases. When creating the analytical model, choose Physical to Analytical for Building.
It is best to prepare a view before selecting the elements because you must use a selection box to select the elements.
After running the Dynamo graph in the player via the Analytical Automation tool, the analytical element is now associated to the column.
The same method can be applied to the floors and walls.
After you have created the analytical elements, you now need to adjust the analytical model to be connected correctly. Use the align tools or edit the profile.
Eventually you have the structural analytical model done and then you can plan to do the analytical design in Autodesk Robot or Prokon Sumo or another Finite Element analysis package.
