[raj banerjee]

hello , im drawing ductwork to dw144, I want to link a 500 round duct to a 800 round duct, I want the connection to be a round duct shoe branch, the sizes only go up to 315, when I manually change it to 500 the shoe doesnt look proper, is there any where I can download some more sizes??

any help would be great
