Import OBJ and STL files

You can import OBJ and STL files in Autodesk Inventor. The data is imported as mesh objects and are contained in a mesh browser node.

In the Import dialog box:
  • Specify how to save the file:

    Choose where to save the components from the drop-down menu. If you choose to Select Save Locations, the Component Destination Folder becomes available. This setting is not available when the Import command is used.


    Component Destination Folder Sets the location for the part and assembly files created from the import operation. If Save in Workspace is selected, this folder is defined in the Edit Projects panel.

    Note: Specify file destinations that are included in the active project or add the paths to the project to assure that referenced files resolve when you open a file.
  • Specify how to save the Translation Report:

    Embed in Document Select to display the translation report icon , under the 3rd Party browser node , in your new file. To view the translation report, double-click the report icon, or right-click select Edit.

    Save to Disk Select to save a copy of the report to the Component Destination Folder.

  2. In the Open dialog box, select a DWF file that contains markups, and then click Open.
