This section is only of interest if you are using Design Data Management to store your data.

Components created with Creo Elements/Direct Mold Base are stored in the Library 3D class in the Design Data Management system. These components are marked as read only. They are stored in the database only once, thus saving disk space. Components are created from scratch every time they are added to the mold. These components will be replaced by those stored within the database later. This means that any geometry reference to components that are not yet stored in the database, will be lost after the data has been stored to the database. References can be attached to parts which are loaded from the database without any problems. The critical time frame is only between creation and loading the data again.

A tool that supports database alignment is planned to be delivered with a next Creo Elements/Direct Modeling revision. For the time being, please store your data, delete everything in Creo Elements/Direct Modeling and load the data again. After that the components stored in the database will be loaded and you can make any attachment you wish.
