eDrawings Pro 2019 can now write out to WebHTML format. This format can be opened in any HTML5 capable browser. You can see it in this video https://youtu.be/-pnQip7cLew Go to around the 50 second time mark.
There is no SW export option to go directly from SW to eDrawings WebHTML, yet.
That's great news, and a good workaround for the time being.
