It's all a bit too much for a tutorial, so I'll have to fudge it.
How I made the part is in chapter5 tutorial and I didn't do any transform rotate/scale, but I do notice if you change a node size with the toolbar and undo it, it does say something about transform. Don't tell me you can't use the arrow select size toolbar in INK.
I don't really get why it works on some and not on others, because this is the first made from scratch part that didn't work.
