How do you make a pattern for an inside curve?

I have a fiberglass shower stall and the bottom tray is too shallow to keep the shower curtain from blowing out. I want to put a short "wall" of 8" x 1" PVC at the bottom but where the walls come up from the threshold has a slight curve. How to I make a pattern for this so that the PVC fits in perfectly?

Any suggestions? I tried to guestimate with paper but it was so imperfect that I was afraid I'd be using tubes of caulk to get it sealed well.

One more question... before I use silicone caulk on the inside and outside, should I glue it in place first and if so, what type of glue? Loctite makes a power grab for fiberglass tub surrounds...???

thank you

Post a picture of your pan.
I think I'd be looking at a shower door, lowering the curtin rod some, or a heavy duty shower curtin with more weights at the bottom of it before I'd try you idea.

Here's a photo of the pan

It seems like the wall of the pan is only 3 inches high. I hot glued some washers into the hem of the curtain to weight it down but if I bump it, the curtain pushes out. I really want to try and put this PVC molding in there. I don't mind stepping over it as if I were stepping into a tub. I also don't have the $ to buy and install a shower door.

Are you putting this on the inside of the shower lip that is there?

Cut a strip of poster board or 1/8" masonite to fit in the shower side to side and say 4-6" wide.
Put it into place, use a compass and scribe the arch onto it.

Cut or bend your PVC piece and silicone it into place.
Not sure if it will stay in place if it gets kicked a few times.
