Tip Title: File / Open preview thumbnail missing
Author: Dean Petersen–Civil/Geospatial Technical Consultant
When you use the OPEN command in AutoCAD the preview thumbnail on the right hand side has completely gone as below.
There is a registry setting that controls this. Only proceed if you are confident of editing the registry and have made a backup of the appropriate keys beforehand.
If you navigate to the registry key:
HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R20.0\ACAD\E001:409\Profiles\<<Unnamed Profile>>\Dialogs\Select File
(You may also need to check this key for any other Profiles listed as well as the <<Unnamed Profile>>)
The PreviewVisible key should be set to 1. I have seen this apparently happen because of a Disk Scan process run by someone’s IT department.
