<p>Publish each version out of Revit or Navisworks, then let BidLight diff the exports element by element. You get the answer in about 15 minutes, not after a 90-minute meeting.</p> <p>Steps:</p> <ol><li>Publish the new version straight from the model. No PDF exports, no side-by-side screenshots.</li><li>Let BidLight compare it against the last version, element by element.</li><li>Read the change list: what moved, what appeared, what disappeared.</li><li>Open any change and see the issue pinned to the element it concerns.</li><li>Send the client the changes that matter to them, with the record behind each one.</li><li>Close nothing without proof: screenshot, tagged user, model commit.</li></ol> <p>That record is the point. Nobody has to reconstruct who moved a duct or when the slip started. Version history is there, changes are pinned to elements, and the 6am digest already told every owner what they own.</p> <p>One live record inside Revit and Navisworks. You stop losing about 11 hours a week working out which version is current, and the client gets a straight answer before the day is over. A clash caught here costs about $50. Found in the field, $5,000 to $50,000.</p>
