Setting Up AutoCAD File Preview with Autodesk Viewer

Beginning with FileCloud 23.1, if a file has multiple 2D and 3D viewing options, the Autodesk viewer in FileCloud lets users display the different views.

Integration with Autodesk Viewer is available in FileCloud Version 22.1 and higher.
Each time an AutoCAD file is previewed, it is stored outside FileCloud on Autodesk's servers for 30 days.
The first time an AutoCAD file is previewed from your site, Autodesk charges you in flex tokens (cloud credits). Subsequent times the (unmodified) file is previewed, by any user on the site, you are not charged. You are charged again the initial time a file is previewed after being modified.
For information about purchasing flex tokens, see

After you configure FileCloud integration with Autodesk Viewer, when users preview 3D and 2D model data file types, they are shown in Autodesk Viewer.
