I'm trying to skin/loft my airfoils (varying scale/chord and twist) to generate a turbine blade but I keep on getting this error. Can someone point out my mistake or potential workaround?

Error Message: Skin Feature Cannot Produce Valid Geometry

Context: Geometry Engine, while generating Feature Skin?

Every curve should have same number of vertices. Please check it.
Make sure you create it between only 2 curves. If it is successful, you can edit it to add one more and so on.
Please go through help manual for more details

I only used 1 airfoil (NACA 63-815) and only manipulated its chord through scale and twist through rotation. It should have the same vertices right? I tried lofting it with only two airfoils hoping that it was the complexity of having multiple twists that made the error. Unfortunately, no luck. even with only two airfoils (63 815 with different chord length and twist) it won't loft.

Can you please check SpaceCLaim?
If you still want to do it in DM, I suggest you to try first on one simple case and make sure that inputs to skin/loft are correct.
