Git doesn't work very well when trying to version control things which aren't text and are large binary files. There's an acceptable workaround which is only a little awkward with git-lfs.

The general consensus is that putting big files in git means you're doing something wrong and the problem is with your environment not git. (or there are special-purpose tools for your kind of workflow which handle the specifics of your use case, like CAD/CAM/etc.)

Workflows like that generally don't fit into nice little boxes anyway the way source code management does.
