How to fit a circle in trailing edge to model each sections of a blade?
 

Hi

I want to model a blade in DesignModeler. to do this I follow these steps:

1) use 3D curves to import airfoil's point of each sections of blade
2) use sketch projection to project this points to sketch.
3) use skin/loft to loft this section
finally the blade modeling complete

but, I need to fit a circle in trailing edge to model each sections properly, but I can't do it.

How can I do this?
