Big Project (for me)

I am certainly new to curved folding, but not new to sheet metal forming. I have a project that is currently over my head. What I want to do is provide a basic 2D geometric shape of an open obround…Continue

Freeform Origami
Freeform Origami is a design software that allows users to interact with origami forms while altering the crease pattern of the model.
Shawn Fernandez replied to Irene Scudellari's discussion Sheet metal folding"I don't know if it defeats the purpose of your project, Irene, but have you considered making each section or panel a separate piece, bending the general loft shape into each individually and then welding them together to finish the structure?…"
Shawn Fernandez replied to Daniel Piker's discussion Virtual Paper"I think for what she's doing the "bend deduction" caused by plastic deformation would likely be small enough to go unnoticed, especially with the slots cut into the material, they will relieve the internal stresses considerably.
I…"
"I would recommend you refer to Helmut Pottmans book on Differential Geometry, where he shows this problem, and the development (I think). But the best approach for now is to use trial and error with card the same shape as your sheet - then add…"
Shawn Fernandez replied to Shawn Fernandez's discussion Big Project (for me)"Translating sheet material to cylindrical product is exactly what I am doing. What I have works well now, but I know that it is not "correct." It has been developed through trial and error and I want to be able to develop a system for…"
"Hi Shawn - this geometry is typically used in industry to translate sheet packaging material to cylindrical products... biscuits basically! I would recommend you model this in Tomohiro Tachi's free software to model this ; if you look at some…"

I am certainly new to curved folding, but not new to sheet metal forming. I have a project that is currently over my head. What I want to do is provide a basic 2D geometric shape of an open obround slot projected perpendicular to its plane to define the curve in 3D space for a curved fold. For clarification, see the pictures I have attached. Based on the pictures I have seen posted by others on this site, it appears to be a relatively simple task to do just one of these folds from a defined…See More
