Description

Alters the triangulation by connecting an edge to the opposite nodes of the triangles sharing the edge. The return value from this method is the index of the resulting edge. The TIN will automatically have the ITin.IsDelaunay property set to FALSE when calling this method.

Index is the index of the TIN edge to swap.

esriTinEdgeType is assigned to the resulting edge. If you want to ensure the edge is not redefined via a subsequent edit operation that's within close proximity to the edge set it to esriTinHardEdge or esriTinSoftEdge.

Tag is the tag value assigned to the resulting edge. Use a value of 0 if you're not concerned about edge tag values.
