How do I fill text in Creo Parametric when projection

Extrude the text as sheet
Then fill it

Yes, that's an option, the problem is when the surface you want to project to is curved.
I've reached to a solution that is hatching the text from the sketch, then you define the hatch lines so close to each other, that the appearance is like if the text was filled. I know that this is not the same, but it's a valid solution for me.

Thanks for your answer
