Hi cad.supportEC55Z,
Apologies for the delay in getting back to you. This forum thread is actually discussing two different issues:
1. The problem in your original post, that on re-open of your Fusion Drawing in TrueView, one view is shifted on the sheet
2. A problem with Output DWG files not showing the view geometry when opened in non-Autodesk products.
This is in reply to item 1, your initial dimension/view positioning issue. This is a bug and we've tracked it down to some work that was done in the last update to support Rotated views (although you don't need to rotate a view to encounter this).
The problem affects Detail Views. If you look at your png, DWG_TrueView_01.png, you'll see the Detail view B has shifted down on the sheet - it is now aligned with the center of the detail view boundary on the base view. In the short term, to get your drawings out, the workaround is going to be to re-arrange the views on your sheet (in Fusion) and make sure your detail view is aligned with the center of the view boundary. This may require upping the sheet size so everything fits neatly.
Here's a screen capture (using a simple drawing) of what you need to do:

Select the Detail View > Using the center grip, move the cursor over the detail view boundary on the base view > hover over one of the quadrants (3:00 or 9:00 o'clock) or the center, then drag the view out exactly horizontally and place it. Now when you output the DWG and reopen in TrueView, all will be well.
I understand this is not an ideal workaround, but arranging the views this way will allow you to get them out.
Alternately, if you have access to AutoCAD, you can open the output DWG in AutoCAD > Select the Detail view > Select the grip and hit the Shift key to break alignment, then click to place the view. At this point if you save, the drawing will be "fixed."
Apologies again for this inconvenience, we are actively working on fixing this bug as soon as possible.
Thanks,
Chris
