A duct trunk is used for managing ducts. The duct trunk itself has no geometry. Any ducts can be assigned to a duct trunk.
In NET Engineering, users have the option of defining duct trunks themselves. The form is opened by double-clicking in the duct trunk field in the Duct form or in Industry-Model Explorer > Duct > Duct trunk.
