Additionally, the concept of tower sections has been added for the modeling and management of Self-Supporting towers. A tower section is a superset of tower panel (or, bays) all with similar geometry.

Sections conforms to this and allows you to manage each section either in the Properties panel or in a Sections table (similar to the Panels table).
