Rebar.CreateFreeForm(Document, RebarBarType, Element, IList<IList<Curve>>, RebarFreeFormValidationResult) Method

Note: This API is now obsolete.

Creates a free form rebar that will be unconstrained. Constraints can't be added later to this rebar.

Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.4.0.0 (26.4.0.0)

Syntax

C#

[ObsoleteAttribute("This method is deprecated in Revit 2026 and may be removed in a later version of Revit. Please use Rebar.CreateFreeForm(Document doc, RebarBarType barType, Element host, IList(IList(Curve)) curves, RebarStyle style) instead.")]
public static Rebar CreateFreeForm(
	Document doc,
	RebarBarType barType,
	Element host,
	IList<IList<Curve>> curves,
	out RebarFreeFormValidationResult error
)

Parameters

doc Document: A document.
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.
curves IList<IList<Curve>>: Each array of curves represent a bar in the set.
error RebarFreeFormValidationResult%: Will be Success if everything is ok, otherwise the failure reason.

Return Value

Rebar
The newly created free form Rebar Instance.

Exceptions

Exception	Condition
ArgumentException	host is not a valid rebar host.
ArgumentNullException	A non-optional argument was null
ArgumentOutOfRangeException	A value passed for an enumeration argument is not a member of that enumeration

Remarks

The created rebar will have curves.Count bars. The layout will be Single if curves.Count is 1, otherwise will be Fixed Number and will not be changeable. Setting a new list of curves will only change the number of bars in set.

This function can fail due to following reasons:

One or more of the input curves was null.
One or more of the input curves was unbounded.
Curves doesn't form a valid curve loop, it forms 0, 2 or more curve loops.
A rebar constructed from curves can't be bent according to the bending radius (the considered Rebar Style is Standard).
