In terms of drawings being reviewed using the Review process. Markups are added and then corrected by our modellers. Then uploaded to be reviewed again, however, the markups stay on the drawing. Archiving the markups will be too tedious. Please have the markups visible ONLY on that specific version of the drawing, so that when a new drawing is uploaded, it's a "clean" drawing ready for review. If a Reviewer wants to check what the markups were previously, they need only look back at the previous version to see what the markups were.
