I would like to copy selected polygon features to a polyline feature class. (Similar to how polygon features can be copied and pasted inside an edit session in ArcMap)
Until recently I've been using the pPolygon2:ExteriorRingCount, pPolygon2:InteriorRingCount method - iterating through the polygon rings and converting them into polylines and so on... As described in this post I have a suspicion that the pPolygon2:ExteriorRingCount method might not be working in ArcObjects 10.1 (VS 2010 Express, VB.NET)
Although this approach has been working flawlessly until version 10.0 perhaps I am over-complicating things. What is the best approach for copying polygon features to a polyline feature class with ArcObjects?
