CAD. com. VBA is in the process of being phased out, and the replacement is. NET. This may disappoint some of you that have VBA applicationsskills, but you will be pleased to hear that you can still use code that you have, and all you know about VBA programming with Auto. CAD can still be put to good use using VB. NET. 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. What you need. There is no native IDE integrated development environment within Auto. CAD for developing. NET projects like you could with VBA via the command VBAIDE. Instead, you need an external software development package for writing and compiling your code. Fear not however, you can download express editions of several programming suites for free directly from Microsofts website. Click here to visit the page for downloading Visual Basic Express 2. Next, you need to download the Object. ARX programming interface from Auto. Desks website. Click here to visit the page for downloading Object. ARX. Ensure you acquire the correct version of the Object. ARX libraries for your version of Auto. CAD. Create your first VB. NET Auto. CAD project. Open Microsoft Visual Basic Express, and select New Project, and then select the Class Library option. This creates a project that compiles to a dynamic link library. In VBA you automatically have access to the Auto. CAD object, including objects such as This. Drawing, but in this environment we have to create references to Auto. CAD explicitly ourselves. We do this by naming a reference to Object. ARX, which contains the Auto. CAD type libraries that we want to use. Under the Solution Explorer window, right click on your project Class. Library. 1 if you havent renamed it, and select Properties. Click on the References Tab. Click on the Add dropdown, and select Reference. Click on the Browse Tab, and navigate to where the Object. ARX libraries are installed. Typically this will be C Object. ARX 2. 01. 1Depending on your preference, open the folder inc win. Select the dll files Autodesk. Auto. CAD. Interop. Autodesk. Auto. CAD. Interop. Common. dll, and click OK. This imports the Auto. CAD type libraries. Add another reference, and this time select the inc folder. Select Ac. Mgd. dll and Ac. Db. Mgd. dll, and click OK. Im not completely sure why these are required, but apparently they are Finally, youll notice on the References Tab that the Copy Local property of the Ac. Mgd. dll and Ac. Db. Mgd. dll references is set to True. This needs to be False so select them, and under the properties window change the Copy Local property to False. Writing some initial code. Our project is now set up with all the references required to link to Auto. CAD. Now we can begin writing code. Switch back to code view If you havent renamed anything, double click on Class. Solution Explorer. 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 Class. Contains the Auto. CAD Type Library. Imports Autodesk. Auto. CAD. Interop. Contains the Auto. CADObject. DBX Type Library. Imports Autodesk. Auto. CAD. Interop. Common. Now in VBA, we had access to the This. Drawing object. This is quite useful, so it would be useful to have the same functionality here. Now that we have access to the Auto. Quarkxpress 3.1 on this page. CAD object model, we can add a simple Get procedure to retrieve the object we want. Put the following code inside the Class between Public Class Class. End Class. Public Read. Only Property This. Drawing As Acad. Document. Return Autodesk. Auto. CAD. Application. Services. Application. Document. Manager. Mdi. Active. Document. Acad. Document. End Get. End Property. Now we can use This. Drawing anywhere within the class as we could in VBA. Writing our first Auto. CAD Function. Everything is in place now to start producing our own Auto. CAD commands. If you have any VBA code you want to transfer across, you should now be able to paste them into this class. Heres one that I wrote recently as an example. The code adds a border to MTEXT, and the only difference between this code and VBA code is that Ive made use of the. NET TryCatch statement, which is better for error trapping than previous methods in VBA Public Sub Create. MText. Border. Dim ent As Acad. Entity. Dim pnt As Object. This. Drawing. Utility. Get. Entityent, pnt, Pick MTEXT to add a border to. Dim mt As Acad. MText. Dim Min As Object, Max As Object. Dim Coords7 As Double. Get. Bounding. BoxMin, Max. Coords0 Min0 1. Coords1 Min1 1. Coords2 Max0 1. Coords3 Min1 1. Coords4 Max0 1. Coords5 Max1 1. Coords6 Min0 1. Coords7 Max1 1. If This. Drawing. Active. Space Ac. Active. Space. ac. Model. Space Then. This. Drawing. Model. Space. Add. Light. Weight. PolylineCoords. Closed True. Else. This. Drawing. Paper. Space. Add. Light. Weight. PolylineCoords. Closed True. End If. This. Drawing. Utility. PromptInvalid Selection. End Try. End Sub. Make sure that your subroutine is declared Public as opposed to Private, so that it will be visible by Auto. CAD. Also, there is one final piece of code we need to add to make this visible by Auto. CAD. We need to add some META data before the subroutine, which tells Auto. CAD that the subroutine is callable directly from Auto. CAD. This is where we assign our subroutine a Command Name for our Auto. CAD Command Line. Add the following code on the line before Public Sub Create. MText. Borderlt Autodesk. Auto. CAD. Runtime. Command. MethodMTEXTB Whatever we put in the brackets will be the command that we type into the Auto. CAD command line. Our class is now complete, and is ready to be compiled into a DLL file for use with Auto. CAD. Compiling. Under the debug menu, we can select Build to create our. NETLOAD command in Auto. CAD will fail to load the. This is because the. NET framework as the version of Auto. CAD you are using. Auto. CAD 2. 01. NET framework, so we need to tell VB to compile our class using this version. Go to project properties as we did before for adding references. Click on the Compile Tab. At the bottom, click on Advanced Compile Options. At the bottom of the Advance Compiler Settings dialog box, select the Target Framework. NET Framework 3. 5. Click OK. This usually requires closing and reopening the project afterwards. Now we can build our. NET Framework as Auto. CAD, which should make it compatable. It is useful to have the Output Window open, so that we can grab the location of the compiled. You can open this window by going Debug Windows Output. Go Debug Build, and this will compile the. Copy the path of the. Output window, and open Auto. CAD. Type NETLOAD into the command line. This is the command for loading. NET projects. You will be prompted to supply a path, so paste in the path to the. If it worked, it should silently finish the command, i. Now that the. dll is loaded you should be able to type in the command specified in the META data to call the subroutine inside the. Datagrid In Windows Form Application. MTEXTB. I would like to take this opporunity to suggest that you subscribe to my blog if you work with Auto. CAD I have many tips and tricks on the tip of my tongue. I guaranteee that you will find it a valuable resource.
