Problem lofting Airfoil Wing

[achaval.lucas]

Hi guys!

I am having problems when trying to loft my wing. I have an airfoil profile and a point that I'm trying to loft with two rails. When I select the first rail, everything goes well, but when the second rail is selected, I get a warning: The loft would intersect itself.

I upload a simple screencast and CAD File, so that you can understand it precisely.

Thanks a lot!

Lucas.

There's a problem with your profile- the lines at the trailing edge overlap each other, creating a self intersecting surface when lofting.    On a separate note, why so many spline points?     You should be able to achieve a close/identical curve with far fewer points.

I created a two-spline profile and successfully lofted along your rails; it seems something is amiss with your profile.

Thanks a lot! Very helpfull.

If possible, take care to connect the rails at the extremes of the cord profile.

I´ll do it. Thanks again.
