Hi, 

I am trying to use the "create points along line" feature in ArcPro to add points to a section of pipe (the points are varying distances). The report I get measures the distance from the beginning of the pipe segment to each of the points. The problem is that when I add the distances in to the table it seems that ArcPro is counting the distance from point to point instead of, from the start of the line segment to each individual point. Is there a way to configure the feature to account for this?

The first point is 52.4 feet from the start of the pipe, the second point is 106.2 feet from the start of the pipe, and so forth.

The remaining length counter is at -613.968 because I think the feature is reading this as, 106.2 feet from the first point there should be a second point. 

Thanks for your help in advance!

@JRine You can use the Offset tool for your workflow: https://pro.arcgis.com/en/pro-app/latest/help/editing/create-features-along-a-line-at-an-offset.htm

Make sure to use 0 ft as your offset.

I hope this helps.

Calculate Field Python examples—ArcGIS Pro | Documentation

see Calculate the accumulative value of a numeric field.

if you need to accumulate values from the start, aka a cumulative sum if the distances represent a segment length

I believe you are correct, the values for the 2nd, 3rd, 4th and so on from the 1st point, then the 2nd point and so on thus the -613.968.  I did some quick math and got the distances between the points to equal out to a final line length of 331.932 and was then able to create the points along the line.  I agree there should be a check box to have the distance values be from the start of the line always to create the points in your workflow...
