Hi,
I am struggling to think of a method to build folded paper lamps, any advice please you can give me pls?
I’d like to understand the workflow to create the shapes I need in Rhino 7 (I have 6 shade visuals to finish by tomorrow morning… I don’t know how to use Grasshopper and don’t have time to learn for this project ).
Rhino file attached is just of the basic shapes. I started building with a zig-zag line but stumbled at the first hurdle as not been able to space / join successfully (I tried to array along the circle curve but I’m not sure how to ensure they meet (if that’s the start of the workflow for this!?)).
There are also pictures in the file showing basic sketched shapes and inspiration images of paper pleating.
Select star shape and run _EditPtOn command, then use _SelCircular command to select inner points and move downward 2.5 units. Edited to change this step from “upward 2.5 units” to “downward 2.5 units” (see post below)
Select the bottom curve and run _ScaleNU make sure copy is checked - origin point (0), X-axis scale factor 0.5, Y-axis scale factor 0.5, Z-axis scale factor 1
Draw a line between 2 corresponding points on the curves.
Hi Kyle,
Thanks for your reply. I am fine creating the flat zig-zag curves to loft for the vertical folds but not sure how to accurately create the curves for the horizontal folds… and how to you loft horizontally so the zig-zags widen as they reach the outer pleats? Excuse the stupid questions, it feels like it should be really obvious!
Once I can do that, I’m sure I will have questions about how to connect using edgesrf, blend, etc!
Hi Kevin,
This is great, thank you … my brain needed this step by step guide (and I am a visual learner)! You have answered my question about the joins and how to achieve the angled shapes where the surfaces meet. Looks simple now I see it…I will try this now!
I noticed an error in the instructions in my previous post. In step #2 I wrote to move the inner points upward when I should have wrote to move them downward. (I edited my original post to correct the wording)
Following the original instructions produces this result which does not mach the photos in your original post:
