I blogged about Autodesk Seek a short while ago and now it's "official". Autodesk officially announced today the availability of the new Web service.
Autodesk Seek provides an online source for building product design information and delivers information-rich results – including relevant design files in multiple formats from within the customer's design applications. Design files can then be easily dropped directly into the designer's building model or drawing, reducing the need to recreate individual components in the design.
This embedded search functionality is now available in the 2009 U.S. versions of Autodesk's Revit-based software applications, as well as AutoCAD, AutoCAD Architecture and AutoCAD MEP. The web service is also available through standard browsers at http://seek.autodesk.com.
