Sometimes Use Rebar API SetHookOritentation methond is invalid

[ChGwo]

When using the Revit project of the structural template, there is no problem creating reinforcement.

When using the Revit project of the building template, the created rebar cannot change the hook direction (SetHookOrientation is invalid), There is another problem, the created rebar plus the hook will produce many rebar shape family types.  Did anyone else find out？

What should I do?

Can you achieve what you are trying to do manually through the user interface in the project based on the building template?
