Rebar.CreateFromRebarShape(Document, RebarShape, RebarBarType, Element, XYZ, XYZ, XYZ)

doc	Document	A document.
rebarShape	RebarShape	A RebarShape element that defines the shape of the rebar.
barType	RebarBarType	A RebarBarType element that defines bar diameter, bend radius and material of the rebar.
host	Element	The element to which the rebar belongs. The element must support rebar hosting; <span class="noLink">[!:Autodesk::Revit::DB::Structure::RebarHostData]</span>.
origin	XYZ	The lower-left corner of the shape's bounding box will be placed at this point in the project.
xVec	XYZ	The x-axis in the shape definition will be mapped to this direction in the project.
yVec	XYZ	The y-axis in the shape definition will be mapped to this direction in the project.
→ returns	nullNothingnullptr→Rebar	The newly created Rebar instance, or if the operation fails.

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).
suppressHooksAndCranks	Boolean	Identifies if the chain will include hooks and the crank 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. This is useful for rebar sets that have varying length bars. In this case you can retrieve the centerline curve geometry of that particular bar, by passing the appropriate index If the rebar set don't have varying bars, the form of the bars does not vary from one index to another.
suppressHooks	Boolean	Identifies if the chain will include hooks 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.

Rebar.GetPresentationMode(View)

dBView	View	The view.
→ returns	RebarPresentationMode	The presentation mode.

Rebar.GetReinforcementRoundingManager()

→ returns

RebarRoundingManager

The rounding manager.

Rebar.HookAngleMatchesRebarShapeDefinition(Int32, ElementId, Int32)

end	Int32	0 for the start hook, 1 for the end hook.
proposedHookId	ElementId	The Id of the RebarHookType
iEnd	Int32	0 for the start hook, 1 for the end hook.
→ returns	Boolean	Returns true if the hook angle of the RebarHookType matches the angle used in the RebarShape at the specified end of the bar.

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).
suppressHooksAndCranks	Boolean	Identifies if the chain will include hooks and the crank 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. This is useful for rebar sets that have varying length bars. In this case you can retrieve the centerline curve geometry of that particular bar, by passing the appropriate index If the rebar set don't have varying bars, the form of the bars does not vary from one index to another.
suppressHooks	Boolean	Identifies if the chain will include hooks 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.

Rebar.GetPresentationMode(View)

dBView	View	The view.
