For non-text blobs, it takes a little bit of insight to get the
most out of them. For OpenDocument (Open/Libre Office
documents), they're zipped files containing text/XML which can be
diff'ed with more meaning. Usually there are custom filters for
git, Mercurial and Bazaar which will unpack the zipped
file contents before committing and give you more sensible diffs.
Likewise, for images (gif/jpg/tiff/raw/etc), there are
particular image-diff programs which make it easier to tell what
happened, as the textual diff of binary files is pretty useless.
However some images (such as .svg files) are XML/text inside,
and diff pretty nicely without extra effort.
I can't speak to CAD/CAE, but it would have to be addressed on a
per-format basis in your given VCS. That said, you *can* store
the binary blobs in each, it's just not as useful without
