I am having issues opening a particular autocad dwg. It was created in 2018. I saved it back to 2013 version and I still have the same issue. I saved back to 2007 version and was able to open it. I'm using this code to open the file, pretty straight forward: DxfModel model = DwgReader.Read(File.Open(curFile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)); I get a System.IO.Exception {"Seeking position beyond end of stream."} I have run the audit command on the drawing in autocad and have found no errors. Any help would be greatly appreciated. Thanks, Robert Flinn I tried to attach the DWG file to this post, but I got a webserver error saying max request length exceded. The file is only 4mb

Can you e-mail the file to wout@woutware.com? Thanks. - Wout

Hi Robert, The problem has been fixed, there was an issue with a certain flavor of 3DSOLID objects. Please download the latest CadLib 4.0 version. Thank you for the report! - Wout
