Rebar.CreateFromCurves(Document, RebarStyle, RebarBarType, RebarHookType, RebarHookType, Element, XYZ, IList<Curve>, RebarHookOrientation, RebarHookOrientation, Double, Double, ElementId, ElementId, Boolean, Boolean)

doc	Document	A document.
style	RebarStyle	The usage of the bar, "standard" or "stirrup/tie".
barType	RebarBarType	A RebarBarType element that defines bar diameter, bend radius and material of the rebar.
startHook	RebarHookType	A RebarHookType element that defines the hook for the start of the bar. If this parameter is <span class="keyword">null</span><span class="nu">a null reference (<span class="keyword">Nothing</span> in Visual Basic)</span>, it means to create a rebar with no hook.
endHook	RebarHookType	A RebarHookType element that defines the hook for the end of the bar. If this parameter is <span class="keyword">null</span><span class="nu">a null reference (<span class="keyword">Nothing</span> in Visual Basic)</span>, it means to create a rebar with no hook.
host	Element	The element to which the rebar belongs. The element must support rebar hosting; <span class="nolink">[!:Autodesk::Revit::DB::Structure::RebarHostData]</span>.
norm	XYZ	The normal to the plane that the rebar curves lie on.
curves	IList<Curve>	An array of curves that define the shape of the rebar curves. They must belong to the plane defined by the normal and origin. Bends and hooks should not be included in the array of curves.
startHookOrient	RebarHookOrientation	Defines the orientation of the hook plane at the start of the rebar with respect to the orientation of the first curve and the plane normal. Only two values are permitted: Value = Right: The hook is on your right as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up." Value = Left: The hook is on your left as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up."
endHookOrient	RebarHookOrientation	Defines the orientation of the hook plane at the end of the rebar with respect to the orientation of the last curve and the plane normal. Only two values are permitted: Value = Right: The hook is on your right as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up." Value = Left: The hook is on your left as you stand at the end of the bar, with the bar behind you, taking the bar's normal as "up."
hookRotationAngleAtStart	Double	The out of plane hook rotation angle at the start of the bar.
hookRotationAngleAtEnd	Double	The out of plane hook rotation angle at the end of the bar.
endTreatmentTypeIdAtStart	ElementId	The end treatment type id at the start of the bar.
endTreatmentTypeIdAtEnd	ElementId	The end treatment type id at the end of the bar.
useExistingShapeIfPossible	Boolean	Attempts to assign a RebarShape from those existing in the document. If no shape matches, this function returns <span class="keyword">null</span><span class="nu">a null reference (<span class="keyword">Nothing</span> in Visual Basic)</span> if createNewShape is false or it will create a new shape if createNewShape is true. When both parameters are "true", the behavior is the same as sketching rebar in the UI. At least one of these parameters must be "true". If the RebarShapeDefinesHooks flag in ReinforcementSettings has been set to false, and a RebarShape cannot be found with both matching curves and hooks, then this method will perform a second search, ignoring hook information.
createNewShape	Boolean	Creates a shape in the document to match the curves, hooks, and style specified, and assigns it to the new rebar instance. Shape creation will not succeed unless one or more other shapes already exist in the document, and these shapes have enough shape parameters to define a shape for these curves.
→ returns	Rebar→nullNothingnullptr	The newly created Rebar instance, or null Nothing nullptr a null reference ( Nothing in Visual Basic) if the operation fails.
