Help with a two line sweep

[ysnyder]

I have one line that I am trying to sweep between two other curves to make a new surface. I have included the file and an explanation of my goal in a Word document. Can one of you help show me the commands I would use to accomplish this goal? Thank you so much!!

Shouldn't the angled lines be tangent to the arc in Sketch2?
What should the Radius of the arc in Sketch2 be (right now it is 1.5096154)?
What is the intended angle between the two lines in Sketch1 (right now the angle is 118.0034318 and not symmetrical)?

Shouldn't Sketch4 be connected to Sketch1 and 2 and the lines tangent to the arc?

Fully defined sketches...

Hi! This doable. It is just that Inventor does not like the Sweep profile starting from the middle of the path and the guide rail. Extrude the two curves as surfaces. Trim them in the middle. Sweep the profile along the path and the guide rail. Then mirror it with YZ plane to get the other side.

Many thanks!
