Autodesk Fabrication Review is an additional application that gets installed automatically with your Autodesk Fabrication product (CADmep, ESTmep, or CAMduct). Fabrication Review enables stakeholders to view 3D Fabrication models prior to construction without the need for Fabrication software. Fabrication Review can display many file formats, including .CAJ, .MAJ, .ESJ, .JOT, .IFCXML, .IFCZIP, and .BIX, plus .DWG™ files as underlays. Review multiple file formats without the authorizing software. Walk-through highly detailed models for more realistic visualizations of proposed building systems. You can also view the status of a model as tracked through Fabrication Tracker.
