Never Been a Fan of Fusion but I found a neat little function that is called " curvature map analysis " which kind of shows a "stress test" for a smotthed surface.
Will something like this be available for v4 of Moi3d ?

Hi ndrakey, right now it's probably not too likely for MoI v4 - the overall focus of MoI is still going to be on making it possible to model simple objects very quickly and easily. Analyzing surface curvature properties generally belongs to a more fancy technically oriented toolset than what MoI is mostly focused on and so it's not really on the radar as being a focus area. I think it will happen eventually though but only after more work on the basics.

What is it that you're trying to achieve with the results of the curvature analysis? If you're trying to analyze stresses on a manufactured part, a curvature analysis tool won't really give that information directly, you need to look into FEA (Finite Element Analysis) tools for that.
