Context
Reusable objects such as drawing frames or title blocks are usually inserted from a
catalog. The component instances are linked by default to the catalog. When a drawing
contains 2D components that are linked to a catalog, problems can occur in case of data
exchange.
2D components can be exposed or exploded after or during its creation. Exposing or
exploding a 2D component cuts any existing link between a 2D component instance and its
reference in a catalog, by creating (from the reference in the catalog) a 2D component
reference on a detail sheet.
