I need to change pipe sizes to 1/2", 5/8", 3/4" or 7/8" diameter, but the program is not allowing it. 1" diameter is the smallest pipe you can change to in Properties. Does anyone know a way to do this?
Solved! Go to Solution.
1/2" and 3/4" sizes should be included by default, at least with RMEP 2012. Verify under Manage Tab » Mechanical Settings » Pipe Settings » Sizes. Ensure that the "Used in Size Lists" box is checked.
Thanks for the Reply. I did what you suggested but the problem persists. When I draw my Copper Pipes the results are the same. The pipes sizes start at 1" and will not allow me to select or enter a size lower than that. It also will not allow me to enter a fraction even when accompanied by a whole number. Is there another setting that I am missing?
Check "project units" Manage>Project Units.Common>Length>Rounding>Pick a Nearest fraction of your choice. OK out of that and check if you have fraction pipe sizes.

In addition to this, there are a few other things to remember.
You notice the pipe has some parameters under Mechanical called Material, connection type and class.
MAKE SURE the new size you are adding to copper matches the same connection type and class.
Thanks for your reply.
How do I check that "the new size you are adding to copper matches the same connection type and class."
Thanks in advance.
I found this thread because I was having a similar problem - I could only see whole number diameters- in my Project Units/Discipline/Common, the length had a fraction. So I then changed the Discipline to Piping and saw that pipe size rounding was set to 1". After I changed that to a fraction, I was then able to see all the pipe sizes.
