So it looks like our Branch Line here just got brought up again. That's why it's always a good thing to check as we're designing. It'll be an easy fix.
Let's delete this piece of pipe and we want to match this to the other Branch Lines, which are, if we select this one, 10 foot six. We'll go to our drop-down, select 10 foot six and connect into the main. Okay.
Let's proceed with now connecting our sprinklers to the Branch Line. Start with this one. We can shorten our section.
Okay. Now we're looking at this sprinkler right here. These ones, we have two options; in this case, let's just do an offset.
So starting with this sprinkler here, let's delete the fitting. Let's make both of these one inch, take this piece and we'll move four inches. Okay.

We'll offset that one and the next sprinkler we'll do a typical Arm Over. Okay. So AL for Align.
There we go. Start with the closer sprinkler, delete the 90, move four inches for our offset. Okay.
And the last sprinkler with a longer Arm Over line. Okay. We can pull it back a bit.
Let's go ahead and cap that later. When we do some refinements, we can make sure everything else is capped, but it's good to do it if you remember it now. Okay.
We've got one last Branch Line to do and our piping in the classroom and corridor areas will be complete.
