If the vault support conditions are defined for the solution together with the building, the vault is solved interactively with the structure. Vault analysis is already done with the Analysis + Design (F9) command.
If the vault support conditions are defined as a separate solution with the building, the vault solution is made with Dome + Vault Analysis.
