Divide closed spline, parametric surface

Joseph,

I know you are the best modeler and you can make any type of construction in the simplest possible way. I know that you will do anything for money, but not everyone is like you and can help people who are just getting started in this program. This pain probably comes from the fact that you yourself spent a fortune on training, because of which you did not earn enough to graze on the beach, but you spend this time venting frustration here. I understand if you want to help, but if you have to add very visible comments that criticize me, then do not write here. Go make money on models and lie on the beach for the rest of your life.

You can do that or just rotate the end result to match a slope.

The question may seem “trivial” to you but the answer is definitely not.

Dude, I have never charged a penny for my Rhino/GH work. That post is insulting :bangbang:

This is what you want I guess.

about data management questions, this is way more complicated than a question to answer here. I would recommend watching some tutorials.

This version uses Network Surface to close the ends and intersections with an ellipse to shape the ‘Height’ (blue group slider). :wink:

Atoosa, Joseph,

Yours concept is good. I am greatfull for your answears and ideas. When i merge your ideas togheter i will get what i want. One surface with moving middle points. I have to figure it out how merge your ideas.

Thanks for answears

I’m fed up with this. don’t have idea how to create curves here

Antoosa,
don’t know why the network surface, which joseph proposed, didn’t work in your file. then would be a one smooth surface than 3 merged.

on the other hand in joseph file i can’t create transverse arches.

If you joseph would create map graph with moving middle points it could be done

Versions ‘a’ and ‘b’ above divided the edge curves so the section curves were unevenly spaced. This version ‘c’ fixes that. The ‘Steps’ slider (yellow group) is the number of section curves. I set it to 48 because it closely follows the ellipse (in front view).

that’s look good. Almost solved. one more question. is elipse in the middle necessary? Cannot be a curve where i will be able to move in Z direction those points ? I’m impressed joseph how unconventionally you approach the topic.

This version (‘d’) is an absurd exercise that has sliders in the gray group for creating a yellow NURBS curve down the middle, used instead of the ellipse for shaping the top. It consists of two white points (controlled by two sliders in white groups) with a line between them. Four zero-to-one sliders (‘P1’, ‘P2’, ‘P3’ and ‘P4’) move points… Oh, good luck! The curve is well-formed but limited in shape due to the construction method. Goofy :red_exclamation_mark:

What can I say joseph, even you were teasing me, you have been responding for every issue. I will add a little bit flexibility to this file (I belive i will do), but you acctualy solve the problem. For me this data tree is mind-blowing and way of thinking impressed me. I hope that you know some more tricks and if I would have a problem you will help me, even if you have to take out your emotions on me because of my incompetence. Thank you
