Typo, thanks for starting this thread. I joined this DOpus forum with a few questions I hoped to find answers to, and "How do I view .dxf and .dwg thumbnails?" was the most important.
Besides viewing CAD thumbnails, what do you see if you try to look at a CAD file in the DOpus Lister Viewer pane?
The reason I'm curious is that a couple of months ago I installed the "Free Brava DWG Viewer"
http://www.infograph.com/products/dwgviewer/DWGdownload1.asp
which I learned about in a DOpus forum thread from 2005:
[url]Autocad Dwg Viewer Plugin]
In the thread linked above, someone pointed out the program, calling it a "dwg Desktop and ActiveX viewer," but they said they had not tried it.
I have installed it & can confirm it works with Directory Opus 8.
Now I can preview my .dwg files and zoom in and out, but in thumbnail view mode, the thumbnails were the default icon, and didn't really show a true thumbnail of each specific file.
Now that I've installed the "CAD Preview Image" program you linked above, I can now also see thumbnails of these .dwg files.
So, thank you!
