I have already created my pipe run and my profile. I had forgotten to change the pipe size in the pipe settings before doing this so all of my pipes in the run came out at 8" when they should be 12". Is there and "easy" way to fix this. It seems like you should be able to edit data and change the pipe size number to 12", but it woun't allow me to do this. I might just be totally missing something obvious. Thanks, Amanda
