offsetValue	Double	The distance from references to the rebar handle.

RebarConstraint.IsReferenceValidForConstraint(Reference)

Became obsolete in 2027: This property is deprecated in Revit 2027 and might be removed in a future version. Use the RebarConstraint.isReferenceAValidFaceForConstraint().

targetReference	Reference	The reference to be checked.
→ returns	Boolean	Returns true if reference can be used in a constraint of 'ToFace' or 'ToCover' type, false otherwise.

RebarConstraint.ReplaceReferenceTargets(RebarConstrainedHandle, IList<Reference>, Boolean, Double)

Became obsolete in 2027: This property is deprecated in Revit 2027 and might be removed in a future version. Use the new signature of the RebarConstraint.replaceReferenceTargets.

handle	RebarConstrainedHandle	The RebarConstrainedHandle that has this constraint.
