What solution for Cataloging progs to generate thumbs for .3dm?

Hi,
I use AbeMeda and it doesnt generate a thumbs for .3dm
If perhaps the file had a jpg or tiff, I recall a file type called ‘eps with tiff preview’ then it could latch into that and show whats the file is .

Does anyone use cataloging progs and find the same issue ?

Cheers

Steve
