Fold angle question

Davidt33 3 years ago updated 3 years ago 4

Awesome app. Quite fast too from what I see. Just started getting into it recently. Ran into a little snag and hope you can help. This is a display box I've been trying to mock up via Origami. The top opens and supposed to fold midway with the bottom half tucked right down vertically/straight (or almost). I've tried to input all sort of numbers for folding angle/s to get the fold to fold straight down vertically or at least near to so the viewer could see that top half section folded as should be when on shelf, to no avail. The numeric value I've currently input (on each score, left/right of pack extension) to get it to fold down as far possible is 110. Any number higher produces an "Impossible Shape" error. Question is how do I get it to fold more as I want to, or what number/s should I input?

Hope the image attached gives a better understanding of current situation, predicament and what I would like to achieve. Tried to be as clear as possible.

Hello David,

Any chance you can post the dieline Illustrator file here? It is difficult to help without seeing the dieline itself.


Sure. Here you go. And thanks for the prompt reply.

Thanks, so let's have a look:

When Origami shows "Impossible shape" error, it most likely means that something is misaligned and edges don't match after folding. You may notice that it highlights a specific edge with the error. Let's have a closer look at it:

You see the cut doesn't join the crease well. Origami has its own limits for misaligned parts and it seems that when you fold the shape too much, the difference goes beyond the limit.

Fixing this lets me fold the shape more:

You can even set it to 180, but this might give you z-fighting as explained here: https://boxshot.com/origami/tutorials/mistakes/z-fighting/

It is better to replace one 180 degrees fold with two 90 degrees ones like this:

Then you get a nicely folded box without z-fighting:

Hope this answers your question. Let me know if you need any further help with it.

Wow, Wow, Wow, Wow, Vitaly. Such an insightful investigation with an absolutely clear, easy to follow series of explanations and pictorial examples. Truly impressed. I cannot tell you how much I appreciate this. You are truly an asset to your company. I shall fire up Illustrator an Origami ASAP and apply fixes recommended and report back. Thanks again and keep up the good work.
