What’s New in Revit 2021 for Structural Engineers?
Steel Detailing Service:
The bulk of the new structural features this year were aimed at concrete detailing but there are a few new steel detailing features that are worth a mention. You can now add stiffeners using the steel workflows which makes this much easier than the traditional approach of creating a face-based family. The stiffeners can be set to pattern at regular centre spacing and can be one or two sided.
You must be very mindful that when a steel connection or process from the steel ribbon is used then other tools become invalid. For example, you will no longer be able to use the cut or align command. Plates can now be dimensioned and referenced from their centres; this is particularly useful while setting out the new stiffeners.
The concrete reinforcement tools continue to develop and now offer more than enough functionality for all to be able to produce good RC details and bending schedules in 3D along with the added benefits of a fully coordinated 3D model. Although I didn’t mention this in the main text, Autodesk have now added new categories to support linear infrastructure workflows with Infraworks. This will greatly improve the definition of bridges and tunnels and allow each element to be placed on relevant categories.
The steel modeling tools are great for adding extra detail but if fabricators are going to make use of the tool then the fabrication drawing manager and CNC tools really need to be developed and provided within the product.
Structural Rebar>
The Structural Rebar category is the original and main tool for detailing reinforcement in Revit. It can be accessed from the Structure Tab in Revit or from the Modify Tab after selecting a valid object.
You can add a Rebar to an element in many different ways, but the approach I like most is to draw Reinforcement Section perpendicular to the object in question, click on the element and choose “Rebar” from the Modify Tab. Then I go ahead and choose my Rebar Bar (diameter), Rebar Shape and Placement Orientation.
