Fan Blade twist

[ZaC-04]

Hi,

I modelled a blade where it twists between the center hub and blade. How do i get a more accurate shape flow where the twist and blade connect? [Image attached with red circles highlighting the sections]

Is there a twist feature to create this blade shape or a better method than i have used?

Thanks

I did use the Loft [join] originally but it created differences in thickness which is why i used Loft [surface & thicken]. Even if i use a greater distance between the 2 sections the thickness varies. The original part has a small distance between the hub/blade.

@ZaC-04 if this part doesn't need to be parametric, then this is an easy thing for "Plasticity" to handle.
