Is it like a computer program or something
People usually just draw them in Adobe Illustrator or Inkscape or something.Programs that let you "fold" virtually and generate diagram kinda exist but they aren't really suitable for serious stuff and they step images they generate aren't that good.
>>622159wouldn't using serious 3d cad software be better for designing complex models?
>>622150I just followed this tutorial to make my first diagram in inkscape https://www.youtube.com/watch?v=8TMICjVvALcSoon I'll be shilling my own models everywhere!>>622296I know there are ways to mathematically create models but can't you just iterate faster with paper in hand?Then you just trace over photos.I don't think anyone is using physics simulators to create their diagrams. In addition, diagrams often have over-exaggerated proportions on some steps to make them easier to read/understood by the reader (instead of being realistic).
>>622150>How are origami recipes made>Is it like a computer program or somethingFor those who are really serious, there are in fact strings of words or symbols that abbreviate the folds.For example, the crane you posted begins with what we call the "bird base" (step 8). We use this base for many other origami projects, so we all learn how to make it.From there, your crane uses kite folds, petal folds, and reverse folds. A formula of sorts can be written to describe the entire process.
