RebarShapeDefinition.AddParameter

Public Class

Add a parameter to the shape definition.

Namespace: Autodesk.Revit.DB.Structure

Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

public void AddParameter(
  ElementId paramId,
  double defaultValue
)

Parameters

paramId ElementId

The parameter. To obtain the id of a shared parameter, call RebarShapeParameters.GetElementIdForExternalDefinition.

defaultValueDouble

A default value for this parameter in shapes. The default values should be chosen carefully, because they are required to be consistent as a set of constraints.

Exceptions

Exception

Condition

ArgumentException

paramId is not the id of a shared parameter in the current document, or its unit type is not UT_Reinforcement_Length or UT_Angle. -or- The name of a shared parameter identified by paramId was already used by another shared parameter of the element.

ArgumentNullException

A non-optional argument was null

Remarks

A shape parameter must be a shared parameter and have value type double. A parameter must be added to the definition before it can be used to drive the shape in a RebarShapeConstraint object. A parameter that does not drive a constraint is legal and will simply become an editable parameter on any Rebar that is an instance of this RebarShape.
