You have published your models as Factory Assets for using them with the Factory functionalities you have in Inventor and AutoCAD installed from the Factory Design Suite.
In case, you can find here the details for authoring and publishing the Factory Assets.
You have published them as Local User Assets
So, they are available just for the user that has published them.
If you want to make them available for another user of the same machine or on another machine, you need to copy the content of the folder C:\Users\<user1>\Documents\Factory Library and paste them under the folder C:\Users\<user2>\Documents\Factory Library.
Where user1 is the user that has published the assets as described above and user2 is the user that needs to use these assets as well.
By the way, if you want to use these Assets across users and machines, the recommended procedure for publishing them is to define a library path in the Inventor project.
The library folder can be defined, of course, in a shared location on a shared server.
You can find more details in this page under Procedures > Factory asset publishing > Follow this procedure to publish factory assets > Use project libraries for published factory assets.
After doing that, you get the Library folder in the Publish Asset dialog and you can publish the Assets in this folder or in the subfolders you may create.
The Assets published in the Library folder and subfolder will be available for all the users using projects that include the library path you have defined above.
In case you have published the corresponding 2D Assets as well in the Library folder or subfolder and you want to use them as well across users and machines with the Factory functionalities in AutoCAD, you need to add the Inventor project that contains the path to the Library folder in the field “Inventor Project used to define additional libraries”, in the AutoCAD options, Factory Assets tab, Libraries section.
Now, let’s assume you have already published a certain amount of Assets in the User Assets folder and subfolders as explained at the beginning of this post, so they are available just for the user who has used done that.
Then you decide you want to share them across users and machines.
In order to do that with the Assets you have already published in the User Assets folder and subfolders, you define a library path in the project as explained above, copy the content of the User Assets folder (i.e.: C:\Users\<user1>\Documents\Factory Library) and paste them under the folder defined in the Library path of the project.
After doing that, the Assets will be available for all the users using the same project and also for the user using different projects but that contain the path to the Library folder.
Then, from this moment in on, you will start publishing the new Assets in the Library folder and subfolders.
