<p>Most of the time, the model and the sheets are not from the same revision. Doors were added or deleted in one and never carried across, and nobody noticed until the field counted them.</p> <p>BidLight makes the gap visible. Every publish from Revit is a versioned snapshot. Compare the revision the sheets came from with the current one, and the comparison shows which elements were added, moved or deleted, grouped by category. The door changes sit in there.</p> <p>How to close it:</p> <ul><li>Publish your current model from Revit.</li><li>Compare it with the revision the sheets were issued from.</li><li>Read the changes and pin an issue to each door that does not match. The issue carries the sheet and revision.</li><li>Assign an owner and close it with proof.</li></ul> <p>That is how you find the 100-door gap in the model, not on site.</p>
