Parallel lines into a parabolic surface

Hi, I can’t create these red parallel lines. To understand, my drawing will be simpler :wink: Can anyone give me a hint? thanks

Create a linear array and then trim the lines with the boundary.

Use flow to morph everything from 2D to your parabolic surface.

Thanks to your help, I’ve made the parallel lines and will now continue to apply them to the surface. :slight_smile:

You could also project the lines to the surface.

unfortunately the result is not the right one :frowning: If you have another research lead…

Unroll the parabolic surface and use its boundary to trim the lines. Then flow from the unrolled surface to the parabolic
