I'm working on new Snapping Capability of ArcGIS Engine. I want to use snapping capability using ISnappingEnvironment class while users are editing a feature or moving vertices. I tried IPointSnapper.CacheShapes() and set the FeatureSelection of IMap as argument of type GeometryBag but I dont know when I should cache features and clear it or update cache. We are using ControlsEditingEditToolClas control for editing features and I want to use new snapping with this tool or other available options.
