Dividing line into equal parts results in wrong order

[JanetBrewster1]

Hello All,

In Pro 3.4.2, I'm using the Divide tool to split a stream line into 9 equal parts. Pretty basic.

The processing preview looks fine....

But the new reaches, sorted by ObjectID, are out of order. Rather than the first reach being the downstream-most, it's second from the upstream-most. 

When I use the Split tool in ArcMap, it does this correctly (same data layer, same stream line). Any ideas why Pro would do this? Sounds like a bug to me....

Any thoughts would be greatly appreciated. Thanks!

Janet

@JanetBrewster1 you are right there is a difference between ArcGIS Pro and ArcMap in the way the objectIDs are assigned to the divided parts. 

Out of curiosity, why is it important for your use case for the ObjectIDS to be assigned similar to ArcMap behavior?

@JMutunga Thank you for the reply. This is in a much larger context than just splitting a single line -- I was trying to keep the question short, but maybe I kept it too short.

I have a sample frame of 50+ streams, and each stream needs to be split x times (in this instance, 9). This results in hundreds of line segments, each of which needs to be numbered recursively, downstream to upstream (in the same order as the larger streams that are being split). The sequential calculations I have are based on the ObjectID, where it does indeed matter in which order they are spit out. 

And actually, I have XTools Pro, which allows me to batch split, and then reorder as I need. However, I'm working with a partner who does not have access to XTools, so I'm trying to find a solution within ArcMap or Pro that isn't completely onerous.

Thanks for expounding on what you are trying to accomplish. This is something the editing team can look into and we appreciate reporting the behavior to us.

I also wanted to mention that you can use Divide with multiple line features if dividing them into equal parts.

Thank you. Yes, being able to Divide multiple line features is an improvement from ArcMap in that sense, but with the result being out of order, it ultimately doesn't help.
