Recently I ran into an issue when trying to send some CAD files (.dwg) to a client of mine, his email would only accept up to a 10mb file. While most of the time I would just ftp, or host it for him to download, this particular client is not very computer or internet savvy and really only knows how to use his email and other basic programs. So rather than try to walk him through how to download something or access my ftp I simply spent a few minutes trying to shrink my drawing size. While this process isn’t always do able, my particular file was only 13mb so it didn’t need to shrink by much. But these tips will typically work to reduce your size to some extent.
