Attribute rule to split a line feature at a point intersection

StefanAngerer — Mon, 13 Mar 2023 09:15:01 GMT

Hi Esri community,

I want to create an attribute rule that checks if a point feature intersects with a line feature. If there is an intersection, I would like to split the line feature into two, with the point feature placed in between. Has anyone done something similar before? Any guidance or suggestions would be appreciated.

Thanks!

Stefan,

Take a look at this - https://github.com/Esri/arcade-expressions/blob/master/attribute_rule_calculation/SplitIntersectingLine.md

Hi @MikeMillerGIS ,

thanks for the fast replay and very helpfull rule. Im currently testing it and it works quite fine. However what I am trying to find out is, if its possible to also cut the lines when the point is not directly placed on a vertex of the line but rather at some point between two vertizes. Obviously it seems like this case was left out intentionally in the script, however i cant get a hold on why?

Thanks and kind regards!

Nevermind, I just found the uncontrolled-variable. Looks like this is what i was talking about.

Do you mind where you find the uncontroled-variable and how do you insert the vertex by using Arcade?
