Hello there; No, because you must specify a typical beam in the X direction to calculate the ribs in the X direction and add them to the metering, and you must specify the typical beam in the Y direction to calculate the ribs in the Y direction and add them to the metering. If you specify typical beams in the X direction only, you do not calculate and include the Y direction ribs that will actually be manufactured. This is the reason why the metering is low. This situation is definitely wrong. Best regards.
