AddParameter Method

Add a parameter to the shape definition.

Namespace: Autodesk.Revit.DB.Structure
Assembly: RevitAPI (in RevitAPI.dll) Version: 16.0.0.0 (16.0.0.0)
Since: 2009

Syntax

C# 
public void AddParameter(
	ElementId paramId,
	double defaultValue
)
Visual Basic 
Public Sub AddParameter ( _
	paramId As ElementId, _
	defaultValue As Double _
)
Visual C++ 
public:
void AddParameter(
	ElementId^ paramId, 
	double defaultValue
)

Parameters

paramId
Type: Autodesk.Revit.DB ElementId
The parameter. To obtain the id of a shared parameter, call RebarShapeParameters.GetElementIdForExternalDefinition.
defaultValue
Type: System Double
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.

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.

Exceptions
