First off, thanks (again) to Joseph Oster for a post he made late last year. He showed someone how to make twisted columns that were going to be used for a building structure. I saw that and thought I could adapt Joseph’s script to make a 3D printed LED table lamp, which is one of my standard projects.
With some changes and additions based on Joseph’s script I made this lamp geometry:
It is comprised of a base to hold the LED light, a polar array of twisted columns, and a hemispherical top. What I need help with is how to find the outer edge of the polar array:
A close-up of the top of the array shows the problem I have:
The top of the lamp is a hemispherical shell, and this does not accurately fit the outside edge of the array. I’ve tried several ways to isolate/obtain the array’s top outer edge curve, but I can’t find any method that works. As a result I have this kind of mismatch between the top and the array:
Since this will be a 3D printed part (it is printing right now) I think this mismatch won’t be too noticeable, but it would be nice if the top could match the array edge properly. So I’d appreciate any suggestions anyone might have to get these 2 sets of geometry to match up.
I’ll be happy to post my GH file if needed, but I’m hopeing someone can just point me to some method that will allow me to get the top outer edge curve. Thanks in advance for any feedback.
