Documenting in 3D with VW will get you pages and pages of Sections/Elevations (good!).
However, if the viewport caches are not properly saved, then you end up with pages upon pages of blank pages with empty red rectangle frames (no good!).
The problem here is not that we do not render our viewports often enough, it is that updated viewports are not synced properly across the various machines in Project Sharing. The end result after a few rounds of 'save and comment' is that we end up with blank viewports again across all the terminals.
So, if a staff was expecting to 'fix up' something in an elevation we printed out, he would finds himself having to re-render that section/elevation in his machine, because there is no viewport cache. Unfortunately rendering a hidden-line viewport is not a quick process (will post a separate feature request for fixing this).
VW has to better log which VP is the most recently rendered, regardless of when a particular terminal performs the 'save and commit' function.
As an office that needs to produce drawings for issuance. This fix can't come soon enough. This fix really needs to happen NOW.
(and if you were going to ask whether 'save viewport cache' is checked across all terminals. Well, obviously, yes)
