Thumbnail files

[Anonymous]

Where are dwg/dwf thumbnail files stored?  Are they accessible to where I can use them as a thumbnail on a webpage to create a hyperlink directory of dwg/dwf files?  Other posts I researched were asking about thumbnail previews not working so I figure this is a new thread.

They are raster images embedded in the DWG or DWF file: nope, you can't touch them.

So to create a "thumbnail" like I want/need then I would have to plot to jpg (or similar) and go that route.

Gray Technical has a low cost tool to extract thumbnail images (along with drawing properties) in batch and even writes HTML files you can use or merge.

Anthony,

You might have a look at my DwgGrid program which extracts thumbnails (also dwf thumbnails) and from them create html pages with links to the files.

It's been a while since I've updated the program and the output may be a bit crude but perhaps it will work for you.

I'll try it out.
