a Zaha Hadid modeling question

I'm really interested in the Galaxy SOHO project by Zaha Hadid:http://www.zaha-hadid.com/wp-content/files_mf/1449_sohoc_rend_0437.jpg http://www.zaha-hadid.com/wp-content/files_mf/1449_sohoc_draw_01.jpgand i tried to make a grasshopper definition like soit's not so hard to make 4 individual circle towers, but when two circle…See More

"I've got similar problem with few closed curves. Even though that i flip them i gives the sam wrong result. "Reparametrize" option didn't help. Anyway, what "Reparametrize" option does in general ?"

Jim choo replied to Jim choo's discussion why is the LOFT so messed up?

"here is my problem: say I got 10 lines, and the no. 2, 5, 7 need to be flipped, I did exactly what you did in grasshopper, and no.2,5,7 did flip, but the rest of the line reversed as well. why is that?"

Danny Boyes replied to Jim choo's discussion why is the LOFT so messed up?

"The curves are in different directions and need to be aligned before lofting. Use the Flip Curve component and input the first curve as a guide so that only curves in opposite directions will be flipped. "

why is the LOFT so messed up?

I got two sets of lines and tried to loft them up to make a blinds like effect, but the lofting is just so messed up, some of the vector directions are totally different. please see the attached jpg file. does anyone know how to flip some of the curve directions within a list and not disturbing the index order of that list?See More

"If your surfaces happen to be planar then you could make a planarSrf from the Edges of your joined BRep. But I suspect from the image that they are not. In which case you you are going to have to create section curves and loft them. (Thinking out…"

how to convert multiple surface into one?

I got this situation, 3 surfaces in Rhino, connected together with a sharp edge, please check the screenshot.I tried the join command, but it just groups the 3 surfaces together not converts the 3 into 1. so is there anyway to do the converting thing?See More
