CADalytic Media has released a free beta of SpecifiCAD for ArchiCAD 10/11, AutoCAD, ADT, Revit and Sketchup. SpecifiCAD allows you to click on a building component within each of these programs and access its CAD details, 3D models, specifications and Green information using the Sweets Catalog network and the Sketchup 3D warehouse depositories.
