When viewing the xref image directly in Civil 3D on desktop the .sid is a large and dense image which is streamed (Per my troubleshoot with Autodesk). This means the image is constantly regenerating when it is zoomed in and appears high quality. The ACC Docs web viewer doesn't enable streaming, therefore the image is very grainy when zoomed in as it behaves like just a snapshot. This is problematic for my Civil 3D users who are trying to use the ACC platform for its viewing and sharing capabilities to present the best product possible to project stakeholders.
