Structural engineers, especially those who specialize in concrete buildings, often perform reinforcement detailing tasks. There are several features tools in Autodesk® Revit® platform that can assist in rebar creation – they allow you to create group of reinforcement or individual rebars, area reinforcement and fabric sheets. It’s quite ok, because you can use standard shapes or draw unique shape of rebar, define different layout rules, and so on. But anyway, if you need to do that over and over again, it takes huge amounts of time.
So, whilst searching for tools that can help save you time, don’t overlook visual programming tool inside Revit – Dynamo. Even with some basic knowledge and efforts, Revit user can quite quickly learn it and start creating his/her own basic scripts to automate work.
We also chipped in and created couple of scripts using default nodes, nodes created by others and some that we created from scratch, to enable automated rebar placement by using Dynamo. Script can contain from as little as just several nodes to dozens or even hundreds of nodes to automate more situations. Depending on effort and knowledge, you can achieve different results.
This is how one script for automated layout of diagonal rebars around openings looks like, it also searches for situations when there is not enough space for rebars and they should be bent automatically.
Look how it works in one of our example videos – Rebars for openings and wall edges.
So, there are several ways how one can create reinforcement in Revit – using Autodesk Revit reinforcement tools, creating Dynamo scripts on your own, or if you are a user of our BIM solution Precast Concrete - our Dynamo scripts for automated rebar placement are available for free on request.
