This post is about the Dynamo script for reinforcement created during our Precast Concrete webinar entitled "BIM modeling in Revit, CAM, drawings and reinforcement using Dynamo" (hosted May 9, 2019; recording available on YouTube). It should be helpful for anyone interested in modeling reinforcement more efficiently.
During the webinar we added some precast elements and placed connections and reinforcement. We also showed how to auto-generate shop drawings with Revit® and the Precast Concrete add-on developed by AGACAD. For the reinforcement, we produced a Dynamo script to create rebar based on 4 selected edges of the Host element with some simple parameters to control the rebar size and number.
Important notes: This post is intended for Revit 2019 and later editions since some nodes for rebar are not available in previous versions. We also suggest you review the additional Packages added to Dynamo (the add-ons in the image below). The reinforcement settings for Revit elements are already set to the correct values.
