The mix tool was way better before. The red line is a path to which I have added to a shape mix. As you see the path is complex, but the mix does not respect it. I started noticing that the mix tool was behaving funny so i tested this. In previous versions you could make the mix path hand drawn. What happened??
I assume you mean that you want to blend along a path, is that correct?As far as I know it is working as expected in Draw 2020 (build 22.1.1.523).The path you show in your screenshot is rather complicated and the result wouldn't be good looking at all, but I think you should be able to add a Blend to that path without any problem.Select the Blend, click the Path Properties button i Property Bar and select New Path.Then click on the curve/path.Here's my attempt with a smoother curve/path.
