Do features need to be M-enabled for Utility Network compatibility?

AaronManuel2

I am trying to figure out if features participating in a utility network need to be m-enabled as a prerequisite, and I can't seem to find the answer to this in the documentation.

I'm working on setting up some water utility features for utility network capability sometime in the future. They are z-enabled but not m-enabled. We are interested in things like network diagrams and modeling DMA's.

Does this require M values?

Thank you

M's are enabled by default and you cannot disable them. You do not have to fill them out.

As Mike indicated the Utility Network feature classes are M enabled when they are created. If you are deploying your UN as an enterprise you will want to check the box "Allow geometry updates without m-value" in the Feature properties. This will set the M value to NaN when features are created. At this point you can just ignore them.

According to Mike, classes must be m-enabled.

But you don't have to do anything with the m-enablement. At least, we don't, and still it works like a beauty.

Maybe, we'll end up using the m-enablement further down the line, but for a start we don't.

Thank you, so in your utility network, do you have participating features that do not have m enabled? Are you still able to do things like network trace?

AaronManuel2

Thank you. But when I create new features in pro, Z values are checked automatically but Ms are not. The features I'm working with do not have M values. The dataset does have an M resolution/tolerance. So when you say they are enabled by default I'm a little confused. Do you mean on the dataset itself?

Have experience in electric utility and UN only. Yet, I am quite sure, that m-enablement is NOT needed.
