Hey,
I’ve made an ellipsoid from 2 ellipses with RailRevolve and divided it with a grid using ProjectCurveOntoBrep. Then I found the intersections with CCX and connected it with a polyline - saw the solution on the forums.
So far so good but when I took a look at the wire frame I saw that it is not complete. There are lines missing and some connections are not correct (see pic)
Any idea how to solve it?
Hi,
thanks for the help @Jakinta. How did you achieve a complete wireframe as in the screenshot? When I open your edited file, the geometry still has mistakes …
Please, check the white group in file, whatever i have edited is in there.
I had some trouble with mid-Y-axis-plane section, so i had to reconstruct that polyline separately. Have used your existing vertical lines. They are not synchronized with newly generated polylines, hence my note about inaccuracy.
Still have an impression this should be done better somehow…
Wow thanks. Didn’t think about using contours …
Is this the part that connects the intersections on the base ellipse with the contours cause I get zero intersection and I double-checked the inputs (maybe it has something to do with Grasshopper versions, I have an older one …)
No, that is the part for creating horizontal “beams”.
Blue lines in your picture are created within Polyline component, after Sort Along Curve.
Aha, so then there is something wrong with the intersection between the ellipse and extended planar curves. I’ve got zero intersections …
It works on my computer.
It seams that you messed up something with data structure previously in definition.
You can see dashed wire for A input in my file, in yours is solid i.e. flattened…it shouldnt be…
Hmmm … thats strange … I didn’t modify your file, also tried it on a different computer with the latest Rhino version and it’s still the same. Even if I try to recreate the formula in the file the CCX just doesn’t work
hmm…strange…i have reopened the file saved on my hd, same problem as yours occurs… 
It was related to rounding of Z-coordinates. Project those extended lines to XY plane and it is solved.

@Jakinta, @anon39580149 thanks a lot! Both formulas work. 
I started from lines because the axes in X direction are fixed on those 8 double pillars (red colour in the file). Thats why I didn’t divide the length with number of segments but added new axes between those static ones
Do you maybe know how could I formulate that the X lines would generate like that? I tried with scatter but the lengths are wrong
