This year Autodesk strengthen the steel detailing tools with some very useful tools to enable quick and efficient steel connection modelling. Revit is constantly criticised for a lack of model detail with fabrication elements. This release strengthens the 3D detailing capabilities for those that require higher Levels of Detail or fabrication models.
When using the Copy/Paste and editing tools the processing is 20x faster than the previous release and connections can now be automatically propagated. This is due to some smart background processing that calculates the elements that are being processed and allows you to continue with other tasks, the elements being processed are highlighted different colour. The background processing is for steel connections but also works when performing most editing tools. The Background Processing colour can be set in the Options dialog in the Graphics Tab as shown below.
Steel Connections now use types just like other Revit families. This means that you can create various types of base plates and then either select all instances and swap or edit the type parameters. This new feature makes controlling steel connections much easier.
The Propagate tool automatically recognises similarly connected steelwork and adds the relevant connections which greatly speeds up the processes of adding connections. Simply select a steel connection, right click and select Propagate Connection.
Many new parameters have also been added to facilitate the efficient creation of fabrication details such as the new hole parameters dialog box. You can now also set the grip length for bolts to allow for accurate sizing and calculation.
The only missing feature is the creation of automatic fabrication documents and CNC code which I am sure we will see in due course. I would anticipate that this will be a cloud-based tool to take advantage of efficient processing times and could use the BIM 360 products to track versions and store the drawings and NC codes.
Concrete Detailing Tools
This release brings more stability to Revit whilst adding reinforcement bar with slightly different cover settings. Certain elements can cause reinforcement bar to constrain to the wrong faces when copying, mirroring or moving bars. The algorithm has been updated to ensure that rebars remember faces and covers from the original element.
Improvements has also been made to the multi rebar annotations to allow dimensioning to the formwork. Multi rebar annotations can now also be added to freeform reinforcement provided that the reinforcement bars remain parallel.
