High rise tower lofting issue


I COULDNT ABLE TO LOFT … I USED CONTOUR COMPONENET TO THE SURFACE AND CURVES ARE MADE … ICHECKED VECTOR DISPLAY …IT IS IN SAME DIRECTION BUT IF I EVALUATE CURVES…IT DOES NOT HAPPENING PROPER IF I SLIDE REPARAMTERIZING.

No grasshopper file shared - however looking at your screenshot, without knowing more things about your workflow, and assuming you just want to loft all these profiles into one open surface, then you might just need to flatten your curves?

Not sure I follow here, but another one sometimes is curve alignment, not just direction. When lofting, adjust loft options to align sections or make sure to adjust the seams of the profiles prior to lofting.
