Fatal when using ICurve::QueryTangent for a network edge

Last Published: April 25, 2020

Error Message

** Fixed at ArcGIS 8.2 **

When acquiring the polyline geometry of a geometric network edge, if the result returns an empty polyline, using the ICurve::QueryTangent method on the empty polyline geometry causes ArcMap to crash.


This is a known issue.

Solution or Workaround

Use a conditional statement that tests to make sure the geometry is not empty before using ::QueryTangent.
