 You can create a unidirectional link between your external 3D modeling application and your Unity Scene by setting up a Model Prefab Variant to inherit all changes from the Model Prefab. This means that updates to the FBX Model file will flow through to the Prefab.

-If you are working in Unity version 2018.2, you can set up an automatic connection between Unity and your 3D modeling application using a Linked Prefab.

Once you establish the connection, you generally don't have to re-create the connection to bring in any updates.
