In Drainage & Utilities, the option to set multiple barrels for a conduit is available for multiple types of pipe such as circular and elliptical. When setting multiple barrels for a circular pipe, the 3D view updates to show the correct number of barrels, and the calculations also reflect the correct number of barrels (i.e. slower velocity of flow). However, the elliptical pipes do not perform correctly. The elliptical pipes appear to correctly perform the calculations with the inputted number of barrels, but the 3D view does not show the barrels.
