However, I would say that things are about to change. I was hoping that a completely free solution could exist, but when it comes to free and fully-featured vector drawing apps, Inkscape is pretty much the only one on the market, and previously I also would agree that it just doesn't cut it. But Adobe apps are well-known for their relatively higher prices, while Affinity Designer, though much cheaper and are promoted by a group of origami designers, simply doesn't feel intuitive enough to me (it definitely could be just me, since I didn't spend much time digging into it either).

In contrast, commercial vector drawing software such as Adobe Illustrator or Affinity Designer are more popular choices. Perhaps that is due to the fact that many designers have found it difficult to use for various reasons. I drew this diagram using Inkscape, which, despite it being free and open-source software, is less chosen for professional diagramming as much as I know. The diagram is for sell on my Ko-fi shop, but you can preview the results here. In this article, I would like to share some of my thoughts on drawing diagrams. It was quite an interesting task and I really learned a lot from it. Recently I finally completed my first computer-drawn diagram featuring one of my most queried models, Seigaiha without cuts.
