<p>Because every publish adds to it. The record is tied to your Revit model, so when the design moves, the record moves with it. Shift a wall, publish, and BidLight stores a new versioned snapshot beside the old one.</p> <p>Any two revisions compare element by element, grouped by structural, MEP, envelope and interior. Issues pinned to elements keep the sheet and revision they came from, and they close only with a screenshot, a tagged user and the linked model commit.</p> <p>A static markup set is a snapshot taken once, then outdated the moment someone tweaks a dimension. A living record stays as current as your last publish.</p> <p>That is where the time goes back into your week. You stop losing about 11 hours a week working out which version is current.</p>
