We are about to upgrade to Revit from AutoCad here at our office. We are a local home builder and would like to use Revit to gain greater control over the financial outcome of our projects. So here's my question. I plan on loading all of the products we use into Revit, but our building materials supplier changes their prices and submits a price list in the form of an excel spreasdsheet to us every month. Is there a convenient way to update these costs in Revit without going in and changing each one manually? I am open to any and all solutions. Thanks!
