Hi All, @kumara_teja @longt61 @naveen_kumar_t
I’m using Dynamo inside Revit 2023 and I'm attempting to create stirrup rebars for the columns shown in the image below. However, I received an internal error message, and I’m not sure what caused it. Could it be related to a RebarHookOrientation issue when the column is transformed?
As I descibed in the image below, I tick “Include hooks in Rebar Shape definition”,...are my settings correct?
Please check my attached code:
