I’ve been trying to write a DWG that includes a thumbnail preview.

Selecting Write Thumbnail Image hasn’t made any difference to the files in windows explorer.
Is there a tick to making this feature work?
I’ve also looked at other options to generate thumbnail images using tools like the image rasteriser or MapnikRasteriser, but they’ve struggled to generate a good representation of the DWG vector content.

Any ideas on an easy workflow to generate thumbnails for DWG content?

I’d love to just pull an image from the 2D graphics preview within FME...
