Additional Information

The COGO Enabled feature class schema consists of the minimal number of parameters to define 2-point lines, true curves, and spiral curves. Adding additional fields can create inconsistencies and conflicts. Additional fields can be added, and attribute rules can be used to update them on the fly. For example, a chord distance field can be added, and the following Arcade expression can be used: // return chord length given a radius and arclength var r = $feature.radius; //radius var al = $feature.ArcLength; //arclength var chord If (!IsEmpty($feature.Radius)){ chord = 2*r*sin(al/2*r); return chord }

Workaround

Create a new field in the attribute table for the chord distance and use the following formula:

2 * !Radius! * math.sin((!ArcLength! / !Radius!) /2).

Additionally, use the Export ArcMap Traverse File option, as it would have all the fields, including chord length, and a join can be performed with the .txt file and the feature.

Convert the .txt file into a .dbf file using the Table To Geodatabase (Conversion) geoprocessing tool.
