How to add edge to helix sweep?

Hi!
I'm have a sweep along helix over a cylinder.
Depends on the helical pitch, some time I get an edge on the inner part of the sweep and some time I don't.
I actually need this edge because I use it for tangent mate a ball into the bottom of the helix in an assembly.
Here are images to explain.
With helical pitch of 14mm I get the following with edge in the inner part of the thread (I need this edge):
With helical pitch of 16mm I get the following (no edge inside the center of the thread):
Is there a way to add the edge to the 16mm pitch?

Any help would be really appreciated.

I simply added a split line to your contour and did two sweeps, one with each region of the sketch. Is that what you are after?
I do not know why different sizes give you the split automatically...
I haven't tried that yet.
At the end, the goal I want to achieve is to use tangent mate a ball into the helix thread.
The edge was a work around since from some reason I got error when tried to tangent mate the ball surface to the thread surface.
If you have any idea why I get this error and how to do it right, this would be excellent.
