# Arch Elements Construction \[TB]

In this section of the workflow, users can define the construction sequence for arch elements — including the arch ribs, arch bracings, and hangers. All three element types are activated together by a single **Arch Construction** object, with their own self-weight factors.

For more details on the parameters, please refer to the corresponding page.
