In my model right now for a part, I have sketch that will be attached to a helix spiral and later swept. I copied the sketch from another featuremanager in another part and pasted into this part. When I go to make a relation to pierce the midpoint of the long vertical line of threadsection with the spiral helix it says "no intersection found for pierce point." I do not understand why as the other part I just made worked with this option. Any help or information would be greatly appreciated. Here is the part to look at.
