Pipe Sizes?

[Griff]

I have also posted this on the Autodesk forum.

I was trying to add some 1 1/2" pipe, but none of the options on the pull down show any 1/2 sizes. How do I add them? I looked in the PipeSizes.xml file and it shows all the sizes, but when I go to add some pipe and chose the size from the driopdown list, I can't find a single half size in any settings. Does anyone have any idea where I go to add sizes?

It's in Project Units, on the pull down menu select Piping for Discipline and under pipe sizes make sure that you have you rounding set to the nearest 1/8".
