I forgot. Is there a way to force a mainline Class?
We are connecting to an existing mainline and are showing all of the existing POC equipment and meter (as existing) and would like to show the existing mainline too. But since it shares the size of the new mainline, it changes the line characteristic to the new mainline symbol. Is there a way to show and have the hydraulics calculated on the existing equipment while identifying the existing mainline as being a different line type? I know that it can be done manually after sizing, but that leaves a lot of room for human error.

Please no "Cap" suggestions. I know that answer, but that's just clunky.

Steve,
Then I might not be understanding you :) But, the link I previously provided has a "What If You Don't Want Your Classes to Switch Automatically?" section that goes into how to keep a drawn pipe what it was without auto changing when being sized. Give that a shot and see if that gives the results you are looking for.

Steve,
Have you tried Caps? ;)
Seems that you should be able to set a different mainline class through your pipe data, and restrict the sizes so they stick with what is existing (if the performance data allows those pipe sizes when sizing your mainline). Just remember to switch the pipe class when drafting so you keep things aligned with proposed vs existing. Past this, you can always just graphically show the existing items through "dumb" pipes (polylines) and only still keep needed sized pipes done through Land F/X.

Using Multiple Pipe Classes in One Irrigation System Design
Hi Jake,

I may not understand your response. Remember in my post I mentioned that "... since it (the mainline) shares the size of the new mainline, it changes the line characteristic to the new mainline symbol.". So even though I have created a new class that shares the same size as the new class, when I run the pipe size command, it reverts to the class representing the new pipe.

"Past this, you can always just graphically show the existing items through "dumb" pipes (polylines) and only still keep needed sized pipes done through Land F/X." - But I do want the existing pipe to be calculated.

My concern is that sometime, someone will run the pipe size command and forget to manually change this portion of mainline back to existing. Then a Schedule will be run and the existing mainline will not show up in the schedule.

Note: The existing and proposed pipe sizes are the same size.

  • How can we show the existing mainline with a different line type and layer on both the plan and in the schedule while still being able to run pipe sizing at any time and have the schedule updated.
