Autodesk DWF Viewer

[#1]

Hello, I am a french user so sorry for my bad english language.

From MEP 2011 some of my Dwf or Dwfx export files can't be displayed in ADR2011 (last version).

Error message is "file display problem"!

my OS is Windows 7 64b.

Thank you for your help.

Thank you for your question. 

After downloaded the attached two files, I found the first one (Escaliers extérieurs.dwf ) can be opened well but the second failed to open. I investigated the second file and found there is something wrong in this file. The internal W3D file is invalid so this is a publish issue. 

I suggest you can send your question to AutoCAD MEP discussion group. 

Please let me know if you have any other question.
