Hi
I remember reading somewhere that more origami models are open back because some design issue but I went back to my ODS book (which is where I think I saw that information) and couldn't find the explanation. So would anyone please enlight me?

Re: Closed back models more difficult to design
If I recall, it’s because only the part of the flaps that project beyond the base are effectively usable for shaping. In addition, it’s next to impossible to achieve color changes in that region of the model.

Re: Closed back models more difficult to design
Really? I thought most models were opened bottom, because you can’t see underneath the model that well.

This is very interesting. I thought this was common knowledge and that I had just forgotten.
Balton must be in the right direction I think.

Re: Closed back models more difficult to design
If you look at satoshi Kamiya's models, like the mammoths, smilodon, unicorn, and others, I'm pretty sure most of them are open bottom. It makes it easier to make thick bodies.
I think Genuine Origami by Maekawa has some information on this, but it's been a long time and I don't quite remember what it said.

Re: Closed back models more difficult to design
The unicorn is open-back. The mammoth and Smilodon are both closed-back if memory serves, however.
One thing I’d like to know (as I don’t have the paper or the time to experiment) is whether models like the Ryuzin are open- or closed-back. Ryuzin seems to be closed-back except for the head, judging by the “twist” I’ve heard talk of. Can anyone confirm?

Re: Closed back models more difficult to design
I'm pretty sure ryujin 3.5 is open belly. I haven't folded it myself, but I know there are scales along the spine that would be near impossible with an open back model.

Re: Closed back models more difficult to design
I think its actually a weird kind of open back. The spines come from the edge of the scales, which are then wrapped around the body, and end where they reach the spines
