    How do I join a helix to a line using an arc, with the line being perpendicular to the helix axis?

      Hi all,

       

      Was hoping someone could help me with this problem I've been battling with for a couple of days.  I have a 3D sketch with a helix (created by converting entities).  The axis of the helix is vertical (the Y axis), the line is sitting on the top plane along the Z axis.  I have an arc connecting the two but if I make the arc tangent to both the helix and the line then the sketch is over-constrained.  If I remove the relation between the helical spline and the spline from which it was created, then I can have the arc tangent to both the line and the helix, but the helix is under-constrained.  Any ideas on how to tackle this?  I'm pretty sure that an arc that is tangent to both is logical and ought to be possible.  I've attached a picture of the sketch and the part itself.

       

      Thanks,
