Hi dynamo friends,  
I am trying to create stirrups by ungrouping a set of stirrups rebar by using this method in Revit API [CreateFromCurves](https://www.revitapidocs.com/2020/b020c9d5-6026-b9fa-7e23-f6a7ec2cede3.htm)

nd i am pretty sure that the **Bends and hooks are not included in the curve definition**

```auto
`new_rebar = Rebar.CreateFromCurves(doc, rebar_style, rebar_bar_type, start_hook, end_hook, host, rebar_direction, curves, start_hook_orien, end_hook_orien, True, False)`

```

this is the method i collect the curves :

```auto
rebar_curves = rebar.GetCenterlineCurves(False, True, True, MultiplanarOption.IncludeOnlyPlanarCurves, 0)

curves = List[Curve](curve for curve in rebar_curves)

```

Exception: An internal error has occurred.

But when i trid to do only one item in the curves the code work and give me a stirrup with one curve shape (as link stirrup)

Do i miss any thing here ?

Thanks in advance

Are you able to provide the full code? It’s a bit hard to review when there are no images of the graph or code to assist
