This file is a TrustedDWG last saved by an Autodesk application or Autodesk licensed application.

Does anyone know how to resolve this error: "Autodesk DWG. This file is a TrustedDWG last saved by an Autodesk application or Autodesk licensed application."?

I have already done:
- I opened the truedwg software and converted it to autocad 2013;
- I used the EXPORTC3DDRAWING command;
- I saved as;
- I have already used the commands: audit and purger
- I have already opened the file on another notebook with a professional license (mine is a student one);
- I opened another file that had no problem at all, and now it is giving the same problem;

It's not an error but rather a confirmation that the drawing was saved with an Autodesk application rather than a DWG knockoff.

Hi @Gabrielrafaelns 

While this message is informational letting you know you are opening a legitimate DWG file, you can turn it off by setting the system variable DWGCHECK = 0

Hope this help,

It's not really an error. My real problem is that when I export the layout to the model (right-click on the layout tab and export to model) my C3D closes. The only thing I noticed that was "different" was this warning.

But after doing a lot of research and talking to some friends, we realized that the problem was, for some reason, a dynamic block.

I exploded the block using the burst command and the problem was solved.

Anyway, I really appreciate your feedback!
