Propeller design

Hi there, i=B4m designing a boat propeller, based on naca profiles created on matlab. I created 8 profiles and a point at maximum radius. Then i tried to do the loft, using 2 guide curves passing by the extreme points of each profile (one curve pass by the leading edge, and the other by trailing edge). The problem is the blade tip: when i use check entities, it says that some faces are inconsistent, so i cannot knit surfaces later with the shaft. How do i do the blade tip? (i tried to create more profiles in the tip, but all of them are extrapolated and the tip gets deformed). If you want more detail, i can send you an image.

hope you understand my english, thanks, Marcus Almendro

You would be much better of using a solid loft from the start, instead of surface lofts that you knit. Extend the blade into the shaft and join them with a boolean.

I tend to agree I've just had this problem with lofted surfaces on an aircraft wing tip. It was all fine and wonderful for creating the shape, but when it comes to turning it into a solid - forget it. Recreated the wing in solids and had shorter simpler feature manger history with which I could create mold splits. Don't get me wrong surfaces are cool for creating shapes and probably less processor intensive, but the transition to solids is frustrating to say the least.
