AutoCAD.NET API Training Labs 2 Lab 1 -Hello World: Accessing ObjectARX .NET Wrappers In this lab, we will use Visual Studio .NET and create a new Class Library project. This project will create a .NET dll that can be loaded into AutoCAD. It will add a new command to AutoCAD named "HelloWorld". When the user runs
the command, the text "Hello World" will be printed on the command line.
Create your first AutoCAD managed application 1) Launch Visual Studio and then select File> New> Project. In the New Project dialog select Visual C# Projects for the Project Type. Select "Class Libra印"template.Make the name "Lab1" and set the location where you want the project to be created. Select OK to create the projec
t.
2) If the solution explorer is not visible in visual studio, you may turn it on by going to "Vie旷menuand selecting "Solution Explorer". This view will allow us to browse through files in the project and add references to
managed or COM Interop assemblies. Open Class1.vb that was added by the NET wizard by double-clicking on it in the solution explorer.
3) In Class1.cs notice that a public class was automatically created. We will add our command to this class. To do this we need to use classes in the AutoCAD .NET managed wrappers. These wrappers are contained in two managed modules. To add references to these modules, right click on "References" in the solution Explorer and select "Add Reference". In the "Add Reference" dialog select "Browse气Select"Look in" and navigate to the
AutoCAD 2007 directory. (C:\Program Files\AutoCAD 2007\) Find "acdbmgd.dll" and select OK. Click "Browse"
again then select "acmgd.dll" and click OK.
Connect to the AutoCAD Managed API -AcMgd.dll and AcDbMgd.dll 4) Use the 0时ectBrowser to explore the classes available in these managed modules. (View >
