Use either planar or network simplify regardless of current attribute awareness.
[Visual Basic .NET] Public Sub SimplifyEx ( _ ByVal planarSimplify As Boolean _ )
[C#] public void SimplifyEx ( bool planarSimplify );
[C++]
HRESULT SimplifyEx(
VARIANT_BOOL planarSimplify
);
[C++]Parameters
planarSimplify planarSimplify is a parameter of type VARIANT_BOOL
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Remarks
The Simplify method, when applied to an m-aware polyline, will not attempt to detect self-intersections, overlaps, etc. You can use this method to force planar simplification of m-aware polylines.
