Hi Pilou, do you mean to save the bitmap data directly into the .3dm file?

This would be possible to do, but it will certainly increase file size a bit... A couple of things might be a little complex, like I might imagine that someone who got a file with an embedded bitmap might want to get the bitmap out of it so they could edit it or something...
