Hey everyone,
I was simply trying to convert a dwg file into a pdf format without opening AutoCAD or any other external DWG viewer. I followed the general outline from the .NET development guide (
http://docs.autodesk.com/ACD/2010/ENU/AutoCAD%20.NET%20Developer's%20Guide/index.html?url=WS1a9193826455f5ff2566ffd511ff6f8c7ca-33b0.htm,topicNumber=d0e50852) along with the help of another developer (
http://through-the-interface.typepad.com/through_the_interface/2007/10/previewing-and-.html
) but I’ve been bombarded with countless errors.
First and foremost, what would be the best format for opening an external file? The DocumentManger.Open() command or the Database.readDWGFile()?
Second, does the DocumentManager.MdiActiveDocument = previously opened file, work at establishing the “current” document? Every solution requires access the “current” document, so would this work?
And does the [CommandMethod("XXXX")] have any significance? If so, what would I use to print/convert a single DWG file? ‘Simplot?’
And lastly, what is the cause of the errors of the form “Autodesk.AutoCAD.ApplicationServices.XXXXX does not have an implementation”? I made sure the “Copy Local” feature of all the references was set to False.
Thanks for all the help!!
