Add one of the half-spheres to a non-flat surface

Hello, I'm looking to add matter (in this case half-spheres) on a non-flat surface. I have not been able to find a method on the internet, and so I am turning to you to try to find a solution. I've already tried to project spheres (or half-spheres) on the surface and then be able to make a revolution, but the results didn't work, because when I want to do a repetition, the spheres all stay in the same plane and are therefore no longer in contact with my surface. I also tried to assemble my half-sphere with the surface, but here too the results didn't work. I'll attach an example as soon as I managed to create it.

Thank you in advance for your answers

Hello, for a sphere, a simple custom repetition is enough.

You must have created the position points of each sphere on the surface.

In my example, I'm using the intersection of the parametric iso curve.

I create the first sphere on one of the points.

Then custom repetition with the previously created intersection points as multiselection.

Hello, thank you for your answer, I managed to do it on a surface like yours, but now I have another problem that arises. I would like to create a network of points at equal distances (with rectangular repetition or something like that) on the non-planar surface, but the problem is that I only have my final surface at my disposal and can't create a curve that follows the edge to create my points.

Hoping you can still help me.

Hello, can you put a CATIA file = or lower than CATIA V5-6 R2018, or an image of your surface.

Normally if you have a surface edge, an edge, you should be able to use the "Extraction" CMD under GSD to create the curve after you have "repetition of points on curve"

Hello, I'm attaching an example that looks like my base file. My problem is that I can't know which curves border my surface and are at the edges. If I can get them, the rest should be done pretty simply.

Thanks in advance

Good evening 

As said before with the extraction option.

 

We recover the 4 external curves that can be used with the point-on-curve repetition.
