Modify a spline in a sketch

[gillesht]

I have a spline in a sketch and want to modify its curvature. I select the sketch and go in Edit mode. I don't see the points used to cerate the spline in order to modify them. Why? What can I do to see those points?

Best regards.

What the heck -- I can EDIT a reply but I can't DELETE it?  This is about as frustrating as the software.
