Overview of the Subassembly class in Civil 3D
The
Subassembly class (AECCSubassembly) represents the basic building blocks of a corridor design. It defines the geometry of a component used in a corridor section through a series of points, links, and closed areas known as shapes. Subassemblies can exhibit intelligent behavior, such as automatically adapting to superelevation or cut/fill requirements (e.g., a slope subassembly adjusting based on cut depth).
