Summary:
When splitting a polyline feature using tools such as Clip, Divide, or conversion to COGO lines, a minor but consistent discrepancy is observed in the calculated bearing of the resulting line segments compared to the original input line. This discrepancy, while small (approximately 0.00003 degrees), is repeatable and unacceptable for high-precision mapping and engineering applications.
Detailed Description:
A polyline feature with an original bearing of 359.97142191134566 (N00°01'43"W) is being split based on parcel boundaries. Following the splitting operation, the resulting line segments exhibit bearings of approximately 359.97138135206296 (N00°01'43"W) and 359.97176028095197(N00°01'42"W). This deviation from the original bearing is not present when performing the same operation in Autodesk Civil 3D using the same source data and coordinate system.
Environment:
- Coordinate System: NAD 1983 NSR2007 StatePlane California VI FIPS 0406 (US Feet)- Confirmed to be consistent across the project and feature class.
Reproducibility:
The issue is consistently reproducible when splitting the aforementioned polyline feature using various methods within ArcGIS Pro.
