In this exercise, you will reference the .NET assemblies AcMgd.dll, AcDbMgd.dll, and AcCoreMgd.dll. After you reference the two files, you will adjust the properties of the referenced files so they are not copied to the build directory.
To reference the AutoCAD .NET API Files
- In Microsoft Visual Studio, click View menu
Solution Explorer to display the Solution Explorer if it is not already displayed. - In the Solution Explorer, on the toolbar along the top, click Show All Files.
- Right-click the References node and click Add Reference.
- In the Add Reference dialog box, Browse tab, browse to the install folder of AutoCAD and select AcMgd.dll. Press and hold Ctrl, and select AcDbMgd.dll and AcCoreMgd.dll. Click OK.
The default install location of AutoCAD is <drive>:\Program Files\Autodesk\<release>. It is recommended to install the ObjectARX SDK and reference the files from the inc folder.
- In the Solution Explorer, click the plus sign to the left the References node to expand it.
- Press and hold Ctrl, and select AcMdg, AcDbMgd, and AcCoreMgd from the References node.
- Right-click over one of the selected references and click Properties.
- In the Properties window, click the Copy Local field and then select False from the drop-down list. Note: Setting Copy Local to False instructs Microsoft Visual Studio to not include the referenced DLL in the build output for the project. If the referenced DLL is copied to the build output folder, it can cause unexpected results when you load your assembly file in AutoCAD.
