Problem when import point file usin C3D COM programming
Make sure you have these Imports:
Imports Autodesk.AECC.Interop
Imports Autodesk.AECC.Interop.Land
Imports Autodesk.AECC.Interop.UiLand
The example I posted years ago worked fine:

Why not use .NET instead of COM?

Have you stepped through your code to determine which line of code generate the error (that is very simple thing to do and very critical information for anyone, who might want to help, to know, and you should always do before asking for help).
If I had to guess, it is this line:
Dim CivilApp As AeccApplication = AcadApp.GetInterfaceObject("AeccXUiLand.AeccApplication.11.0")
that causes the said error, assume a Civil3D session is running while your code executes. Beside the debugging information you need to provides, the couple of key information you also need provide:
1. Which version of Civil3D you are using? the version number you used in the ProgramID (xxx.11.0) must match your Civil3D version. 11.0 here means Civil3D 2017, if I recall it correctly.
2. How the EXE is executed: does it run as regular desktop app by the current log-in user, or run as unattended app for batch processing?
Following code (Console EXE in C#) works for me (Civil3D 2018), where the Civil3D App's ProgramId is "12.0":
class Program
{
static void Main(string[] args)
{
var cadApp = CreateAcadSession();
if (cadApp!=null)
{
Console.WriteLine("Press any key to continue...");
Console.Read();
var civilDoc = GetCivilApp(cadApp);
Console.WriteLine("Press any key to exit...");
Console.Read();
}
else
{
Console.WriteLine("Press any key to exit...");
Console.Read();
}
}
private static AutoCAD.AcadApplication CreateAcadSession()
{
try
{
var cadApp = new AutoCAD.AcadApplication();
cadApp.Visible = true;
cadApp.WindowState = AutoCAD.AcWindowState.acMax;
Console.WriteLine("AutoCAD started.");
return cadApp;
}
catch
{
Console.WriteLine("Cannot start AutoCAD!");
return null;
}
}
private static object GetCivilApp(AutoCAD.AcadApplication cadApp)
{
object civilDoc = null;
try
{
dynamic civilApp = cadApp.GetInterfaceObject("AeccXUiLand.AeccApplication.12.0");
civilDoc = civilApp.ActiveDocument;
Console.WriteLine("Connected to Civil Application successfully.");
}
catch
{
Console.WriteLine("Cannot get Civgil3D application!");
}
return civilDoc;
}
}
Hi Bro,
thanks a lot for your interest
i do not think the problem in Civil 3D ProgramID (xxx.11.0) . because i useing civil 3d 2017 already . also some codes working well like add cogo points,points group,point style .... or get any information from the currently drawing no any problem come ... but the problem only coming with import point file
exactly in (Dim Opt As New AeccPointImportOptions) as shown in the blow image.
* my EXE is executed as regular desktop app by the current log-in user
Accepted solution
Ah, I see what you mean. It is this line that generate the error:
Dim opt As New AeccPointImportOptions
The error message actually provided hint "...class not registered...", which I did not think too much and jumped to the usual suspect of
... = AcadApp.GetInterfaceObject("AeccXUiLand.AeccApplication.11.0")
The reason of this error is that NOT ALL AEC/AECC classes can be instantiated from outside of AEC/AECC context by " As New xxxx" or "Set xxx = New ....". Just as you go with AeccApplication, which you cannot do
Set civilApp = New AeccApplication
You have to do
Set civilApp = AcadApplication.GetInterfaceObject("xxxxxxx")
Because these objects are already instantiated in AutoCAD context as Aecc objects. The same applies to, you guess it, AeccPointImport/[Export]Options class. So, change your code to:
Dim opt As AeccPointImportOptions
Set opt=AcadApp.GetObjectInterface("AeccXLnad.AeccPointImportOptions.11.0")
Following code works form me (the same cope as my previous reply, plus on extra line in red):
class Program
{
static void Main(string[] args)
{
var cadApp = CreateAcadSession();
if (cadApp!=null)
{
Console.WriteLine("Press any key to continue...");
Console.Read();
GetCivilApp(cadApp);
Console.WriteLine("Press any key to exit...");
Console.Read();
}
else
{
Console.WriteLine("Press any key to exit...");
Console.Read();
}
}
private static AutoCAD.AcadApplication CreateAcadSession()
{
try
{
var cadApp = new AutoCAD.AcadApplication();
cadApp.Visible = true;
Console.WriteLine("AutoCAD started.");
return cadApp;
}
catch
{
Console.WriteLine("Cannot start AutoCAD!");
return null;
}
}
private static object GetCivilApp(AutoCAD.AcadApplication cadApp)
{
try
{
dynamic civilApp = cadApp.GetInterfaceObject("AeccXUiLand.AeccApplication.12.0");
dynamic civilDoc = civilApp.ActiveDocument;
Console.WriteLine("Connected to Civil Application successfully.");
var points = civilDoc.Points;
//var opt = new Autodesk.AECC.Interop.Land.AeccPointImportOptions();
dynamic opt = cadApp.GetInterfaceObject("AeccXLand.AeccPointImportOptions.12.0");
opt.PointDuplicateResolution = 4; // aeccPointDuplicateOverwrite
//....//
return (object)civilDoc;
}
catch
{
Console.WriteLine("Cannot get Civgil3D application!");
return null;
}
}
}
Just to clarify again, since I use Civil2018, thus "xxxxx.12.0". You would use "xxxx.11.0" for Civil2017, of course.
