Hi Tom,

This stuff happens. We just start clicking away and then .... Oh no!!!! But it's really not that bad.You won't have to redo your head layout. Here's an easy solution:
1. Using the Irrigation Manager add the desired 12" pop-up to your project (if they're not already there).
2. insert the desired head types (half, fulls, etc.) into your drawing at any random location.
3. Using the match properties button (the one with the paint brush on the icon; the plant or irrigation match properties buttons are both equally effective) click the head that you want to switch out to (the 12" pop-up) and then click all of the heads that you want replaced (the 4" pop-ups).
4. Do the same with the other spray patterns and you're done, none for the worst.

Easy as pie. _ hope that this helps you.

Don't forget to mix a little fun into it.

Seaweed,

That was very nicely put. I was just going to say that Tom shouldn't make those types of mistakes, then you wouldn't have to worry about what to do! But all kidding aside, Match Properties should be your best bet.

Yes, I'm no longer perfect.

I figured "match properties" would be my best bet.

Thanks!

As an even shorter alternative, as long as the nozzles are the same, you could just edit the text description of the head type through the manager. Change the 4" text to 12".
