How to add several straight lines to a DXF file with a console utility?

Question

Programming

Good afternoon.
The DXF file has an object made of curves. You need arbitrary text (automatically converted to curves) or just draw lines to the edge in a DXF file. Ideally through the console utility. In the worst case - something for Linux'a or completely to the edge through PHP.

I will be grateful and glad for any useful information on this matter;)

public static void Main()
{
  // your dxf file name
  string file = "sample.dxf";

  // by default it will create an AutoCad2000 DXF version
  DxfDocument dxf = new DxfDocument();
  // an entity
  Line entity = new Line(new Vector2(5, 5), new Vector2(10, 5));
  // add your entities here
  dxf.AddEntity(entity);
  // save to file
  dxf.Save(file);

  // this check is optional but recommended before loading a DXF file
  DxfVersion dxfVersion = DxfDocument.CheckDxfFileVersion(file);
  // netDxf is only compatible with AutoCad2000 and higher DXF version
  if (dxfVersion < DxfVersion.AutoCad2000) return;
  // load file
  DxfDocument loaded = DxfDocument.Load(file);
