Question

In an ArcMap extension, I need to flip multiple lines from a selection.

The ArcMap Flip button only allow to flip one feature at a time.

What's the ArcObjects equibalent to the ArcMap's flip button?

Answer 1

ICurve.ReverseOrientation should do what you want.

Actually there is a full snippet Flip Line Direction Snippet , available in the ESRI online documentation.

Here is a small extract from it:

ESRI.ArcGIS.Geometry.ICurve curve = feature.Shape as ESRI.ArcGIS.Geometry.ICurve;
curve.ReverseOrientation();
feature.Shape = curve;
feature.Store();
