First AutoCAD App

  • Create new C# Class library targetting .NET Framework 4.8
  • Add AutoCAD Reference : AcCoreMgd.dll, AcDBMgd.dll, AcMgd.dll
    • You can Add this autocad Reference manually and setting property Copy to local to false
    • My favourite method is just add nuget package AutoCAD.NET from Nuget.org or Nodes Nuget Repo

  • Now Delete existing class from C# project and Add new Hello.cs with below code, make sure class will remain public

    using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
using Autodesk.AutoCAD.EditorInput;
using Autodesk.AutoCAD.Runtime;

namespace FirstAutoCADApp
{
    public class Hello
    {
        [CommandMethod("Hello")]
        public void HelloAutocad()
        {
            Document doc = Application.DocumentManager.MdiActiveDocument;
            Database database = doc.Database;
            Editor edt = doc.Editor;

            edt.WriteMessage("Hello Vivek");
        }
    }
}

  • Compile this app to generate dll file

  • Open AutoCAD app and Enter netload command and Select this dll file to load
  • Try Hello command to see if it’s working as expected
  • Next Do Debug Setup for easier Testing
