New projects are created based on a project template. When creating a new project that will be built into a DLL assembly that will be loaded into AutoCAD, use the Class Library template that comes with Microsoft Visual Studio or one of the AutoCAD Managed project application templates that get installed with the ObjectARX Wizard for AutoCAD 2010. Both types of templates are available for the VB.NET and C# programming languages.
After a new project is created, you will need to reference the files that make up the AutoCAD .NET API. For information on referencing the files associated with the AutoCAD .NET API and installing the ObjectARX Wizard for AutoCAD 2010, see .
