# IFC Viewers

IFC files should be reviewed in an IFC viewer after the export. Linking or opening the IFC file a BIM authoring software is not recommended for this purpose.&#x20;

### Overview of free IFC viewers

[**viewer.autodesk.com**](http://viewer.autodesk.com) (free Autodesk viewer) supports 50+ file formats and allows sharing and commenting. Uploaded files are stored for 30 days by default, and can be deleted or extended as needed.&#x20;
