How can I edit List<Curve> of Rebar same as tool "edit sketch rebar"

[Anonymous]

I 'm coding some addin to trim rebar , extent rebar and split rebar.

Problem: I can't find a function in SDK Revit 2017 and SDK revit 2018, to edit/ set List<Curve> of Rebar same as tool "Edit sketch" (path: Modify|Structural Rebar/Mode/Edit sketch)

now, My solution is not good, first, i get Ilist <Curve> of Rebar by 2 function ,

in revit 2017:

rebar.ComputeDrivingCurves();
rebar.GetCenterlineCurves();

in revit 2018:

rebar.GetShapeDrivenAccessor().ComputeDrivingCurves();

I create new List<Curve>, then I create new rebar,finally I delete old rebar = > Problem: Dimension and tags of old rebar will be deleted

Same problem here, have any of you found more elegant solution than deleting and recreating rebar?

If you are creating a free form rebar, you can simply call SetCurves() method.
