Rebar.CreateFromCurves(Document, RebarStyle, RebarBarType, RebarHookType, RebarHookType, Element, XYZ, IList<Curve>, RebarHookOrientation, RebarHookOrientation, 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."
useExistingShapeIfPossible	Boolean	Attempts to assign a RebarShape from those existing in the document. If no shape matches, this function returns null 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.

Rebar.CreateFromCurves(Document, RebarStyle, RebarBarType, RebarHookType, RebarHookType, Element, XYZ, IList<Curve>, RebarHookOrientation, RebarHookOrientation, 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."

useExistingShapeIfPossible	Boolean	Attempts to assign a RebarShape from those existing in the document. If no shape matches, this function returns null if createNewShape is false or it will create a new shape if createNewShape is 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.

Rebar.GetCenterlineCurves(Boolean, Boolean, Boolean, MultiplanarOption, Int32, Boolean)

adjustForSelfIntersection	Boolean	If the curves overlap, as in a planar stirrup, this parameter controls whether they should be adjusted to avoid intersection (as in fine views), or kept in a single plane for simplicity (as in coarse views).
suppressHooks	Boolean	Identifies if the chain will include hooks curves.
suppressBendRadius	Boolean	Identifies if the connected chain will include unfilleted curves.
multiplanarOption	MultiplanarOption	If the Rebar is a multi-planar shape, this parameter controls whether to generate only the curves in the primary plane (IncludeOnlyPlanarCurves), or to generate all curves, (IncludeAllMultiplanarCurves) including the out-of-plane connector segments as well as multi-planar copies of the primary plane curves. This argument is ignored for planar shapes.
barPositionIndex	Int32	An index between 0 and (NumberOfBarPositions-1). Use the barPositionIndex to obtain all the curves at a specific index in the distribution. You can use GetNumberOfBarPositions() to verify if a specific rebar has more than one bar positions. Use GetDistributionType() to probe if the bars in a specific rebar have a varying shape. If so, you can retrieve the centerline curve geometry of that particular bar, by passing the appropriate index. When the distribution type of a rebar set is uniform, the form of the bars does not vary from one index to another.
suppressHooksAndCranks	Boolean	Identifies if the chain will include hooks and the crank curves.
→ returns	IList	The centerline curves or empty array if the curves cannot be computed because the parameters values are inconsistent with the constraints of the RebarShape definition.
