I have found the section in help and am using 'Change Route Diameter'. When I deselect 'Automatically select elbows & pipes' it only shows the configurations for 'Pipe 4in' (Sch 40, 80, 120, 160) and not for any other pipe diameters. How do I change the pipe diameter to something else? Do I need to rebuild the entire route?

Thanks,

Bevan
