Rule applies to pipe only runs

[Hidden_Brain]

i searched these forums but did not find an answer on this. I have a bunch of pipes which are flagged with a warning called "Rule applies to pipe only runs". for these pipes, the pipe proterties window will not report the min and max cover. the pipe rule i have currently set is a "pipe to pipe match" with match location as invert and drop value as zero, and a cover only rule with min cover 2' and max cover 15'. the structure rule i have set has "sump depth" of zero, and a "pipe drop across structure" set as invert reference and a drop value of zero.

can someone please shed some light into this message?

From the Help on Pipe Rules, so I guess the warning is telling you that you need a different rule:

Pipe To Pipe Match Rule

This rule governs how a pipe elevation is determined in a pipe network that contains only pipes (no structures), and or when a pipe is inserted onto an existing pipe to break the pipe.

This rule applies only during the following conditions:

• Creating a pipe network that has pipes only (no structures)
• Breaking into an existing pipe with another pipe
• Connecting a pipe to a null structure (pipe to pipe connection with no structure)
• Connecting a pipe to an existing pipe end

This rule manages conditions so that only continuous runs of pipe are created as typically expected. In pipe networks where the pipe size is constant, pipes connected to other pipes must to match end to end. In pipe networks where pipe sizes change, the point where pipes match may change, depending on the type of system. For example, in pressure systems, it may be typical to match the pipe centerline. In gravity systems, it may be typical to match the crowns of the pipes.

This rule also incorporates a drop value for cases where a pipe-to-pipe connection requires a drop amount.

i think i understand what you said jeff, but in my case, i have hundreds of structures connected by pipes. why am i seeing this warning then?

this warning is not earth shattering, but when i am looking at the pipes in tabular view, i want to see the red cross marks on those which violate a rule (cover or slope or so). due to this warning, the software flags a bunch of pipes which otherwise do not have any issues (or so i think :-))

You have structures, therefor you cannot appply a rule intended for pipes with no structures. Well, you can apply it but you will be greeted wityh that friendly message you don't want to see. Remove this rule from the set of rules applied to these pipes.

I noticed that you applied a "PIPE TO PIPE MATCH" rule. This rule is specific for networks without structures and that was the cause of the program warning. If you just remove it, you'll not get any other warning.

Maybe somebody will read my comment and be happy that a brazilian guy 5 years later decided to answer the question and it actualy helped. 😃
