A vane system includes vane segments that each have a platform, a connector box, and at least one airfoil extending between the platform and the connector box. The connector box has a first circumferential side in the form of a male connector and a second circumferential side in the form of a female socket. The vane segments are connected together in a circumferential row with the male connector of each said vane segment being received in the female socket of the next vane segment in the circumferential row. A majority of the male connectors are of a first, common connector length, and at least one of the male connectors is of a second connector length that is different than the common connector length.
