Hi, I am trying to change the rebar shape code using dynamo. But I am getting this error. Could you please tell me the storage type of the Rebar Shape parameter ? I am attaching my graph for your review. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/1/c1913f2466ae11ace0763c6da66a10d946877712.png) [Set Rebar Shape.dyn](https://forum.dynamobim.com/uploads/short-url/p7qKbCCfguMjrM5mPolfP5Y2EOi.dyn) (9.9 KB) ---

Hi, you need first to retrieve the shapes in the project, and then use them to change your rebar: ![RebarShape](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/f/e/fec8da9cf27b0bf949be0f6b9c3573b30df5f8eb.png) ---
