Remarks

Parameters are a generic form of data storage within elements. The parameters are visible through the Autodesk Revit user interface in the Element Properties dialog. This method uses a built in parameter id to access the parameter. Autodesk Revit has a large number of built in parameters that are available via an enumerated type.

Example

public Parameter FindWithBuiltinParameterID(Wall wall)
{
    //Use the WALL_BASE_OFFSET paramametId
    // to get the base offset parameter of the wall.
    BuiltInParameter paraIndex = BuiltInParameter.WALL_BASE_OFFSET;
    Parameter parameter = wall.get_Parameter(paraIndex);

    return parameter;
