The Design Library is like your own personal content library. Teams and Enterprise accounts can search through designs from any project you have access to and add it to your current project.
Unlike the Content library, you do not have to nominate specific geometries to be part of the design library. Rather, the design library allows you to add geometries from any project in your portfolio.
The Design Library only imports geometries, usages, and property definitions.
To import analytics, us the analytics import function.
To import layers, use the layer library.
