Autodesk | Design Review 2013 ((link))

1. Introduction & Purpose Autodesk Design Review 2013 is a free, standalone application designed for viewing, marking up, printing, and tracking changes to 2D and 3D design files. Its primary purpose is to enable non-CAD users (e.g., project managers, clients, estimators, shop floor personnel) to participate in the design review process without needing expensive, complex CAD software like AutoCAD or Inventor.

If you are maintaining a legacy pipeline that requires DWF markups and runs on older Windows versions, Design Review 2013 can still get the job done—just be aware of its limitations and lack of future support. autodesk design review 2013
