Trying to edit a polyline feature class in arcscene I cannot get feature vertices to snap to one another.
Snapping tolerance is set to 10 pixels.
In the snapping environment window, all boxes are checked: vertex, edge and end for the layer in question; edit sketch vertex, edge, perpendicular, topology element and node.
I am editing vertices with the edit vertex tool on the 3d editing toolbar, and am moving them in the z direction by holding down z while dragging.
Is there anything else to try?
