Convert dxf created with Vector Draw to dwg

[Mr-Skribbls]

I'm very new to CAD files especially conversion so I may just be missing something. I'm trying to convert a dxf file that was created using Vector Draw to a dwg file. I've created a basic console app as a proof of concept. I'm using the basic examples shown on this repository to read and write. The problem is I'm getting messages I'm not sure what they mean, and the result is not what I expected. Any help will be appreciated.

Here is my code:

-- MyConverter.cs --

///

/// Read a dxf file
///

/// dwg file path
public static CadDocument ReadDxf(string file)
{
CadDocument doc = new CadDocument();
using (DxfReader reader = new DxfReader(file, CadNotification))
{
doc = reader.Read();
}
return doc;
}

///

/// Write a dwg file
///

///
///
public static void WriteDwg(string file, CadDocument doc)
{
using (DwgWriter writer = new DwgWriter(file, doc))
{
writer.Write();
}
}

// Process a notification form the reader
private static void CadNotification(object sender, NotificationEventArgs e)
{
Console.WriteLine(e.Message);
}

-- Program.cs --

static void Main(string[] args)
{
Console.WriteLine("What is the path to the file you want to convert? ");
string filepath = Console.ReadLine();
string dir = Path.GetDirectoryName(filepath);
string filename = Path.GetFileName(filepath);
string dwgFilepath = Path.Combine(dir, Path.ChangeExtension(filename, ".dwg"));

CadDocument doc = MyConverter.ReadDxf(filepath);
MyConverter.WriteDwg(dwgFilepath, doc);

Console.WriteLine("Press any key to close");
Console.ReadLine();
}

When using the app to convert a dxf I get the following messages:
[AcDbViewportTableRecord] Unhandled dxf code 361 with value 123276
[AcDbDimStyleTableRecord] Unhandled dxf code 345 with value 123203
[AcDbDimStyleTableRecord] Unhandled dxf code 346 with value 123203
[AcDbDimStyleTableRecord] Unhandled dxf code 347 with value 123203

The result looks like this

The expected result should look like this

Its likely I'm missing something but I'm having trouble finding what it is. Any help will be appreciated.

Hi @Mr-Skribbls,

Your code is correct, the problem is that ACadSharp doesn't have an implementation to read the subclass AcDbMInsertBlock.

I'll create an issue to address it and fix this issue.

Thanks for the report!
