From a customer:
Art, we are doing a hospital that has say 1500 heads per
floor x 6 floors on armovers. When we go to tag the piping, the branch lines
are say 1.5” the arms are 1” and the mains are 4”. Since the mains are on a
different layer, they are easy to put tags on, but going through each piece of
line making sure not to tag the arms with 1.25” piping is tedious and time
consuming. And forget about having to retag them again if there is a water
supply change or if your calc doesn’t work. Is there any intent in the future
of possibly putting the armovers on a different layer so tagging them would be
as easy as tagging mains and lines with no arms?
My response:
Yes, there is a plan for the future – but right
now you have another option:
- Pick Size Pipe Setup
- Select 1” for the armovers
- Check Use Directional Filter and select the
orientation of the armover pipe – Horizontal or Vertical. The Size Pipe routine
will only size those pipes that match the selected orientation - Note also that there is an option Do Not Resize
Pipes Already Sized. This means that if there is a size already on a pipe, it
will not get another size, even if it is selected. This, along with the
Directional Filter should make it easy to size those branch lines and armovers
