Kinks removal - organic roof


I need help refining my organic roof. I like the shape I have now, but there are some kinks, and the curves are not as smooth as I would like. I would appreciate it if you could give me step-by-step help since I am not very familiar with Rhino. So far, to make this roof shape, I have used the loft command and control points.

Thank you in advance for your help.

Hi Nicole - it looks like you’ll need to Untrim then move a couople of control points out where they are making the suerface fold under-’



move it out a bit
then re-trim.

The ‘kinks’ in the edge curves here:

are there because your surface does not extend past the trimming curve:


Use ExtendSrf to extend it slightly past the trim in Top and then retrim

Your extensions may be wacky due to the folded in corners so fix those first.


Hi Pascal,

I wasn’t clear in my first post why the kinks happened, but that’s where the roof will be resting. I have attached the most up-to-date model I have.
