Solid Tools > Subtract for the Win!!!

Thank you, Rich!!

Hello...This is my first post. Been using SketchUp for a while now and typically when I hit a challenge, I usually can mess around long enough to figure it out, but this one has taken more time than I'm embarrassed to admit!

I'm trying to combine the 2 curves depicted in the attached images into 1 piece. That attached shows the original piece with no curves, then the first curve and then the second. I've tried everything in my wheelhouse and nothing. Any assistance will be greatly appreciated.
