Hello there,

Is there a way to change the look length through a DYNAMO routine. I am currently able to generate the rebar but when I add the hooks, the hook length is bigger than its host, a structural floor.

I know how to manually edit it inside REVIT, according to the following print.

However I can’t edit it within the DYNAMO routine. I have already tried to manipulate it by the parameters by name nodes. Even though they don´t respond with error when i run the program, they don’t do what I intend either (i currently don´t know what they do 🙄).

Thank you in advance.
