How to place a Beam (structural Framing on a line using C# )

Hi Guys, I am trying to place a beam on a line that I am creating for educational purposes, however, the Beam is not created. So my question is how can I insert a Beam (Any beam of any type ) on a line that is created via C#.
To make it simple . I want a beam of any type to follow a line using C# . I have tried this code but It didn't work.

public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
{
// Get the active document and application
UIDocument uidoc = commandData.Application.ActiveUIDocument;
Document doc = uidoc.Document;

// Define the start and end points of the line
XYZ startPoint = new XYZ(0, 0, 0);
XYZ endPoint = new XYZ(30, 0, 0);

// Get the level to place the family instance on
FilteredElementCollector levelCollector = new FilteredElementCollector(doc)
.OfCategory(BuiltInCategory.OST_Levels)
.WhereElementIsNotElementType();
Level level = levelCollector.FirstOrDefault(e => e.Name.Contains("Level 1")) as Level;
Transaction tt = new Transaction(doc);
tt.Start("ss");
// Create the line in the project
Line line = Line.CreateBound(startPoint, endPoint);
SketchPlane sketchPlane = SketchPlane.Create(doc, Plane.CreateByNormalAndOrigin(doc.ActiveView.ViewDirection, startPoint));

tt.Commit();

// Get the family symbol to place on the line
FilteredElementCollector symbolCollector = new FilteredElementCollector(doc).OfClass(typeof(FamilySymbol));
FamilySymbol symbol = symbolCollector.FirstOrDefault(e => e.Name.Contains("Ahmad")) as FamilySymbol;

if (symbol != null)
{

// Place the family instance on the line
using (Transaction t = new Transaction(doc, "Place Family Instance"))
{
t.Start();

FamilyInstance instance = doc.Create.NewFamilyInstance(line, symbol, level, StructuralType.NonStructural);

t.Commit();
}

}

First of all, and before raising a question here in the forum, I would suggest that you take a look at the official collection of Revit SDK samples:

https://www.autodesk.com/developer-network/platform-technologies/revit

It includes quite a number of demonstrations on how to create beams, e.g., CreateBeamSystem, CreateBeamsColumnsBraces, CurvedBeam and more.
