Im glad you heard about SDF modeler, because I posted a comment on your channel as I heard you were searching for something like this. Hope this helps.
👍 SDF Modeler is definitely a promising tool, but I will probably return to macOS in the near future, so until a macOS or iOS version is announced I'm afraid I'll personally have to look for an other SDF editor. But I will surely keep an eye on SDF Modeler. 👍
