Is there a simple way that I can attach my sketch lines to the mid point of a curved line? You can see the blue construction lines below from my current sketch. I'd like the end of my lines to meet the midpoint of the grey curved line marked B. Basically I want A and B to meet. If I select the end of the line and the curved line the "midpoint" option isn't present so I can't select it.
You can add a reference point to the curve. Then, inside the reference point command, use the 50% along curve.
Then you could attach your line to the reference point.
Will this work?
