Hello evreyone: I'm programming a tool similar to ArcMap's Midpoint (Feature Constructor in Arcmap). I draw de line with a  INewLineFeedback object and works well, but de mid point is well calculated, but doesn't refresh properly. i'm wondering if someone knows how i can resolve this.... I attacht my code and a screenshot with the trouble.

Any ideas for how to implement this tool. I can now programmatically calculate the closest point to the point where I click. How to force the drawing on the feature containing that point? ... View more

Hello: I'm writing a application in C#; i can select features from the map (one layer loaded). but i don't know merging it into a same layer as i perform on ArcMap. I've read about IEngineEdit, but  i don't know how to use this interface properly. Also, i saw the "CutPolygonsWithoutSelection" sample, but i don't find how to associate the merge function. I hope some guidance with this issue. Thank you for your attention. (PS: i'm from colombia and i'm still learning english,I apologize for any error in writing ) ... View more
