Include a read-only copy of a project object in a drawing by creating a reference to it.
All the available project objects in a project are listed in the project’s object collections in the Prospector tree.
You access a project object’s data in a drawing by creating a reference to it. A reference is a read-only copy of an object. When you create a reference to an object, you cannot modify the object’s geometry, but you can access its properties and data, apply styles and annotation, and perform some types of analysis.
Creating a reference creates a local copy of the object’s source drawing in your working folder. If you already have a local copy of the object’s source drawing, it is updated to the latest version, if necessary.
