What do you mean with join points? Just draw polylines?

using acApp = Autodesk.AutoCAD.ApplicationServices.Application;
using Autodesk.AutoCAD.Geometry;
//......

private void MyPolyLine()
{
  var doc = acApp.DocumentManager.MdiActiveDocument;
  var db = doc.Database;
  var ed = doc.Editor;
  using (DocumentLock docloc = doc.LockDocument())
  {
    using (Transaction tr = db.TransactionManager.StartTransaction())
    {
      Polyline path = DrawRect(width, height);
      //BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
      BlockTableRecord curSpace = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite);
      curSpace.AppendEntity(path);
      tr.AddNewlyCreatedDBObject(path, true);
    }
  }
}
private Polyline DrawRect(double width, double height)
{
    var pline = new Polyline(4);
    var pt = Point2d.Origin;

    pline.AddVertexAt(0, pt, 0.0, 0.0, 0.0); //Start

    pt += new Vector2d(0, height);
    pline.AddVertexAt(1, pt, 0.0, 0.0, 0.0);

    pt += new Vector2d(width, 0.0);
    pline.AddVertexAt(2, pt, 0.0, 0.0, 0.0);

    pt += new Vector2d(0.0, -height);
    pline.AddVertexAt(3, pt, 0.0, 0.0, 0.0);

    pline.Closed = true;
    return pline;
}
