Currently when editing in ArcGIS (Polygons, polylines, points) snapping to other features is no problem, however, when editing, you cannot snap to the Z values of other features. Points (and vertexes of polygons and polylines) are automatically given 0.000 for the elevation (z value)… (Budget: $30-$250 AUD, Jobs: Anything Goes, C Programming, Cartography & Maps, Python)
