<p>BidLight reads the model&#39;s geometry and metadata when you publish, and stores it as a versioned snapshot with its own files, author and milestone.</p> <p>You publish straight from the model in Revit. Then you compare any two revisions element by element, grouped by structural, MEP, envelope and interior.</p> <p>What it means for you:</p> <ul><li>No more waiting on someone to walk the model and tell you what changed.</li><li>No more chasing emails. When the design changes, publish again.</li><li>Findings that hold up in a meeting, because every change traces to an element.</li><li>Issues that close with a screenshot, a tagged user and the linked model commit.</li></ul> <p>Plans are priced per license, billed annually or monthly: Basics $260 a year ($30/month), Core $330 ($39/month), Complete $440 ($51/month) and Max $590 ($69/month), with Enterprise custom. Every plan includes unlimited projects, and AIA members get up to 29% off. Request a demo to see it on your own model.</p>
