Loft Not Following Guide Curves

[Anonymous]

Hey All,

I am trying to create a loft that follows the two guide rails shown in the screen shots.  As can be seen, the shape is not following the back curve, but I would like it to.  Is there something that I am doing incorrectly, or a better way at tackling the issue?

@Anonymous - I think it actually is following the rail in the middle of the face.  That face is highly concave.  All that rails guarantee is that the surface follows it in that area.  If you want a different shape on the sides, you might have to add more rails.  Can you share the model here, so we can say for certain?

Thank you for the quick reply.  Just for further information, I have included a screenshot of the part I am trying to reverse engineer.  The screenshot shows the body I am trying to replicate using the loft command.

Here is the link to the part.  Hopefully this works:

thanks for sharing the design @jesse.hatton93 .  In the screencast below, I show one way to do this, using 3D splines.  The technique of using the tangent handles to shape the curve is the key.  Use Move to move these handles in 3D.  In the screencast, I was not very precise, you'll want to be more precise.  But, hopefully the idea comes across.

here is another way to do this, using Project->Intersection Curve:
