Creating equal panels on a curved surface with tapering corkscrew

unhandled

(Daniel J Thompson29) #1

Hi, hoping someone can help, I have this tower design with an outer facade that conically tapers along a helix. I have attempted through step by step iterations to work out how to turn the surface into a series of equally sized (ish) panels. I got so far and then the tapering of the shape affected the radius of the surface which required the angle of the panels to change. From the uploaded files (hopefully a rhino and grasshopper file) you can see the mess that happens with the ‘panels’ near the top of the tower.

Any help would be appreciated.

I attached a different approach to how you might solve this problem. It is a little simpler and may give you more control. It uses PanelingTools for Rhino (http://www.food4rhino.com/app/panelingtools-rhino-and-grasshopper).

I hope it helps

Hi

Thanks for getting back quickly, I still ahve the issue at the top where the smaller radius forces to panels to rotate differently is their anyway to adjust panel size/rotation as it goes upwards?

See if the attached works for you. I varied the distance and angle.

Did you notice this other thread? Looks similar.

Yeah that as my first iteration but after trying a work around my self I progressed it a step further and then hit the latest stumbling block

Oh. Two threads, same topic, same person, subtle difference…? The little details I worked out in the other thread, like the ability to change the Arc tangent angle, don’t apply here? The objectives in that thread were clearer than this one. What a pity.

not sure if this will help, the panels are pretty easy to do, depends on the approach, i am not sure if you needed gaps between them, that would be easy to do also,

the versions i made has an option to change the curvature of the profile, you could also attach this to a range and this create less or more curved profiles during the overall sweep / lofted sections
