Is it possible to have a field hanging off the length automatically re-calculate when the length changes?

Is it possible to have a field hanging off the length automatically re-calculate when the length changes within ArcGIS Pro (2.4).

Essentially i have a series of vectors that represent fences so there is a field that divides by the nominal length of fence sections and then spits out a value. When i edit the vector i have to re-calculate. Is there a way for the field to update itself automatically to remove the need to this?

Many thanks!

Rob,

You could use arcade expressions to calculate a length on the fly, then divide it by either a fixed value or a field representing the nominal length of fence sections.  Below are some resources to help you get started:

• Arcade Geometry Function - Length
• Arcade Expressions Operators - Division
• Configure pop-ups ArcGIS Pro
