Starting in eDrawings Viewer 2019, all previous functionality included with eDrawings Professional 2018 and prior are now included in the free eDrawings Viewer version. This only applies to the Windows application only (not the mobile eDrawings App).
NOTE: Any new features added in eDrawings Professional 2019 and onward will only be available with an eDrawings Professional license (i.e. saving as a Web HTML introduced in eDrawings Pro 2019)
As an example, the Measure tool was only available in eDrawings Professional 2018 and older (though there was one scenario where eDrawings Viewer could measure). Now eDrawings Viewer 2019 has full access to the Measure tool.
