AUTOCAD 2011 TUTORIALS CODE

Put the following code inside the Class (between Public Class Class1 and End Class): Now that we have access to the AutoCAD® object model, we can add a simple Get procedure to retrieve the object we want. This is quite useful, so it would be useful to have the same functionality here. Now in VBA, we had access to the ThisDrawing object. 'Contains the AutoCAD/ObjectDBX Type Library We need to specify in this class which libraries from our references we intend to use, so right at the top of the class (before Public Class Class1) put the following code: 'Contains the AutoCAD® Type Library Switch back to code view (If you haven’t renamed anything, double click on Class1.vb under Solution Explorer). Our project is now set up with all the references required to link to AutoCAD®. This needs to be False so select them, and under the properties window change the Copy Local property to False.

Finally, you’ll notice on the References Tab that the Copy Local property of the AcMgd.dll and AcDbMgd.dll references is set to True.

I’m not completely sure why these are required, but apparently they are! Select AcMgd.dll and AcDbMgd.dll, and click OK.

Add another reference, and this time select the inc folder.

This imports the AutoCAD® type libraries.

Select the dll files and .dll, and click OK.

Depending on your preference, open the folder inc-win32 or inc-圆4.

Typically this will be C:\ObjectARX 2011\

Click on the Browse Tab, and navigate to where the ObjectARX libraries are installed.

Click on the Add dropdown, and select Reference.

Under the Solution Explorer window, right click on your project (ClassLibrary1 if you haven’t renamed it), and select Properties.We do this by naming a reference to ObjectARX, which contains the AutoCAD® type libraries that we want to use. In VBA you automatically have access to the AutoCAD® object, including objects such as ThisDrawing, but in this environment we have to create references to AutoCAD® explicitly ourselves.

This creates a project that compiles to a dynamic link library (.dll file). Open Microsoft Visual Basic Express, and select “New Project”, and then select the “Class Library” option. Create your first VB.NET AutoCAD® project Ensure you acquire the correct version of the ObjectARX libraries for your version of AutoCAD. Click here to visit the page for downloading ObjectARX.

Instead, you need an external software development package for writing and compiling your code. NET projects like you could with VBA (via the command VBAIDE). There is no native IDE (integrated development environment) within AutoCAD® for developing. The following tutorial sets the foundation for creating your first VB.NET project, and should serve as a good starting point for migrating your code across to VB.NET. This may disappoint some of you that have VBA applications/skills, but you will be pleased to hear that you can still use code that you have, and all you know about VBA programming with AutoCAD® can still be put to good use using VB.NET. VBA is in the process of being phased out, and the replacement is.
