A feature to allow the user to define default element values such as pipe diameter when creating a new model would be helpful. Right now, in US unit system of measurement for the software, the default pipe diameter value is set at 12-inches. Much more common pipe diameters are either 6 or 8 inches. It would speed up setting up/drawing a new model by allowing the user to set the defaulit value to 6 or 8 rather than drawing everything in as 12 and then going to each pipe to change 12 to the more common value.
