You can use special tools and workflows when you work with very large models such as plant layouts.
You can define connection points and a ground face in part and assembly models and publish the models as assets. When you insert an asset into an assembly, magnetic mates snap the asset into position relative to other assets.
You can create a SpeedPak configuration of an asset directly in the Asset Publisher PropertyManager. Using SpeedPak configurations can greatly enhance performance, especially in very large assemblies. However, you cannot use entities from an existing SpeedPak when creating an asset.
