<p>In about 15 minutes, compared with a 90-minute coordination meeting. BidLight compares any two revisions of your Revit or Navisworks model and lists the differences element by element, grouped by structural, MEP, envelope and interior.</p> <p>Each publish is a versioned snapshot with its own files, author and milestone. When the design changes, you publish again and compare, so you stop chasing scattered updates.</p> <p>That speed is what lets you show a client what their change touches before the meeting ends. Then the questions stop and the sequence conversation starts. Issues pin to the elements, so owners see what to fix in their 6am digest.</p> <p>Pricing is per licence, billed annually or monthly:</p> <ul><li>Basics: $260 a year, or $30 a month</li><li>Core: $330 a year, or $39 a month</li><li>Complete: $440 a year, or $51 a month</li><li>Max: $590 a year, or $69 a month</li><li>Enterprise: custom pricing</li></ul> <p>Every plan includes unlimited projects, and AIA members get discounts of up to 29%.</p>
