CAD Viewer is a viewer: it does not create or edit CAD geometry. Proprietary 3D solids in DWG, external references, and the full geometry of closed formats (Revit, SolidWorks, Inventor, CATIA, ACIS, Parasolid) are not displayed.

View, measure, mark up, and export CAD drawings and 3D models with a fast, reliable, and private mobile viewer.
