So the main issue here seems to be the scale of the data. For example, I examined one mesh and found the x values ranged from about 0.98 to 1.5. Unfortunately, ShapeWorks has some issues with very small and very large scale data that we are working on resolving. Right now, the best range is 0-100 or so. If these are human aorta in mm range, then they should have already been in a good coordinate space.
I scaled your meshes by 100 and played with the parameters a bit.
It’s not the best model, but it’s heading in that direction:
