Dxf and dwg creation export has no option to create image for thumbs

Rhino Rhino for Windows

Hi,
V7

File explorer win10 can show thumbnails for .dxf and .dwg files.

from an internet article:-

Solution:

Make sure that the drawing file is set to save a thumbnail preview image

  1. At the Command prompt in AutoCAD, enter THUMBSAVE and set the value to 1.

  2. Save the drawing file to update its thumbnail image.

I try that in Rhino v7, but there is no option I can see to save a thumbnail preview image.

I have installed FastPictureViewer but it doesnt make thumbs for those., it seems to not deal with the CAD and graphics world.

As progs making such files have this thumbnail maker, how can Rhino do this ?

Rhino saves thumbnails as part of the 3dm. When installing Rhino it installs also a shell extension that gets the thumbnail out and passes it on the Windows file explorer when asked by it.
