That is the same basic thing, just the math is different. That would be no more complicated to make in grasshopper than the original problem. Start with the basic input parameters in the diagram. The exact math can be built into your shape. After that, you can shatter the various curves if needed. I am not sure what your question is?
The issue is that I’m new to Grasshopper, so I don’t know how to create the .gh file, could you please help me
Sure, I will look at it later and post a script. It is something different. Even my Tekla CC creator found the problem unique, and he has been doing this for a long time. The new diagram will largely use point inputs and expressions that are your forumla’s. Once you have the curves, it is no more different than revolving in Solidworks. You can do this in Solidworks as well using variables, but if you are planning to use this with Tekla, grasshopper is better.
If you see a benefit to grasshopper in your work I suggest taking a course. If you search some of my posts from a year ago you will find the struggles I was having. Thankfully, I found a number of really helpful people here that were kind to help. This program is a bit of a beast to learn, but it is worth it. I still fight with data maniupulation at times, but my scripts now are far more efficient.
Talk later.

I created your new dome geometry.
Some notes:
- There are sliders to adjust the dimensions of the shapes.
- You can see the basic curves geometry used to find the dome geometry in the front view.
- The script creates the inner shape of the dome by finding the intersection points and creates half of the inner dome profile.
- The dome outer profile is a simple offset, and the dome is a revolve.
- Both the 2.0 domes and 1.9 domes are included. One is green, and the other is blue.
- The formula values are not to sufficient significant figures to find exact intersection points. There will be a mathematical solution, but I did not have the time. I assumed the SF values, and DH values would be correct and adjusted the KR formula until there was one intersection point between the curves.

Thank you for your help—it worked perfectly in Rhino!
However, I’m not sure how to import the model into Tekla Structures.
Could you please assist me with this?
Thanks in advance!
There is no simple solution to import directly into Tekla from this point as mentioned earlier. If the goal is to build this I would do most of the plate work in Rhino, and import the flattened platework into Tekla to track all the parts. To do that you will need to split the various arcs into the dimensions needed before you do the revlove. If the goal at this point is a simple illustration in Tekla, then you can split the dome geometry into mutliple levels (10 - 20) and loft between the circles. The plate geometry from lofts will not be very useful, but you wil get a decent picture.
You may want to post on the Tekla forum to see if you find any that specialize in this type of work. There may be another solution. Given @sebastian.lindholm comments, I don’t think there is a simple solution.
I only need it for geometric modeling, not for flattened platework or detailing.
The best method for illustration purposes is to import a baked rhino version into Tekla. I have done that many times with site data. If you want native tekla parts you will need to split up the arcs and create reference curves to use in Tekla as lofts. I am not sure how well the lofts will section at intersection points. I expect there will be gaps where the plates intersect and you will need to edit the drawings. The rhino data will be a watertight shape that should section perfectly. I do not have time today to illustrate this.
