public static void Main()
{
	string path = "sample.dwg";
	CadDocument doc = DwgReader.Read(path, onNotification);
}

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

For more examples check.

The dwg/dxf readers are not yet fully implemented, the NotificationHandler will send a message to inform about the objects that could not be readed or any other error in the process.

ACadSharp has the first DwgWriter in an early alpha.

Compatible versions:

• AC1014 - Release 14, 14.01 (LT97/LT98) - (WIP)
  • Produces a valid file but the entities are not in the model.
• AC1015 - AutoCAD 2000/2000i/2002
  • This version depens on the implementation of VP_ENT_HDR to work properly with the different Viewports
• AC1018 - AutoCAD 2004/2005/2006 (MOST STABLE - RECOMENDED)

• AC1021 - AutoCAD 2007/2008/2009
  • This is a particular and isolated version for DWG, it uses a different compression system and file distribution, due this difficulties, this version will not be implemented any time soon.
• AC1024 - AutoCAD 2010/2011/2012
• AC1027 - AutoCAD 2013/2014/2015/2016/2017
• AC1032 - AutoCAD 2018/2019/2020
  • This versions have a similar structure than AC1018 but the file that is generated by the current writer seems to be missing something, they need further investigation.

IMPORTANT NOTE when you open a file writen by ACadSharp with Autocad the following message will appear: The drawing file requires recovery press on Recover and it will open the file normally. This process this may cause a loss of information on the file.
