Ah, "ArgumentException", isn't it obvious enough: you passed wrong type of data into one of the argumnets of the AcadDocumkent.Import() method.
Look at the method's signature carefully: Import(string FileName, object InsertionPoint, double ScaleFactore).
The second argument is the equivalent of "Variant" in VBA, representing a 3-element array of doubles, NOT an AcadPoint object as you did!
The insertion point should be an double array of 3 elements.
The sample code (a console app that automate AutoCAD and does the importing) work OK with my Acad 2009. Since I do not have *.dgn file, I used *.wmf, which should not matter, in term of inserting error you have gotten.
using System;
using System.IO;
using Autodesk.AutoCAD.Interop;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
AcadApplication app =null;
try
{
app = new AcadApplicationClass();
app.Visible = true;
}
catch(Exception ex)
{
Console.WriteLine("Canot start AutoCAD: " + ex.Message );
return;
}
string file = "E:\\Temp\\test.wmf";
if (!File.Exists(file))
{
Console.WriteLine("Cannot find file: " + file);
return;
}
Console.WriteLine("Press any key to start importing...");
Console.ReadLine();
double[] pt = new double[] { 0.0, 0.0, 0.0 };
AcadDocument doc = null;
if (app.Documents.Count > 1)
{
doc = app.ActiveDocument;
}
else
{
doc = app.Documents.Add("acad.dwt");
}
if (doc == null)
{
Console.WriteLine("No drawing is open");
return;
}
try
{
doc.Import(file, (object)pt, 1.0);
}
catch (Exception ex)
{
Console.WriteLine("Importing failed: " + ex.Message);
Console.ReadLine();
return;
}
Console.WriteLine("Importing done...");
Console.ReadLine();
}
}
}
Have you really read my first reply?
You CANNOT pass an AcadPoint (e.g. the variable "insertPoint" in your code) to the Import() method's second argument! AcadPoint is an AcadEntity (a visual presentation of a point), not a geometric point (an array of 3 double element).
Also, since you do out-process Acad automation, you CANNOT use Point3d as the other post suggest: his code sample is run inside AutoCAD (NETLOADED).
When you said the code I showed is "sadly" not working, I can hardly believe it. Have you done debugging to locate the offending code line? What error did you get? Can you show your EXACTcode that simliar to mine, but not working?
Hmm, that is interesting. The code is the same as mine that proves working (with my Acad2009 and Jeff's Acad2011).
So, what could it be then?
Can you export a *.wmf file from your AutoCAD and then import it manually and then by the code exactly as mine, to just prove that the code, even works for me and Jeff, but still not for you?
Or, are you using 64-bit Acad? No that I know that would be the cause as I know, just try to find out what difference between the your Acad and mine (and Jeff's).
