<p>The issues stay pinned to their elements, and the move shows up as a change. You publish the updated model from Revit, BidLight stores the new snapshot, and you compare it with the last revision in minutes. You can tell the client what the move touched while they are still talking.</p> <p>Every publish is a versioned snapshot with its own files, author and milestone. Compare any two revisions element by element, grouped by structural, MEP, envelope and interior, and you see what changed and who changed it.</p> <p>Issues pinned to those elements keep the sheet and revision they came from, so you can see which open items the move affects. Owners get them in the 6am digest.</p> <p>You walk into the coordination meeting knowing what every change touches. A conflict caught in the model costs about $50, against $5,000 to $50,000 in the field.</p>
