Autodesk Inventor 2013 Loft problem

[essemenov]

I try to make motorcycle tank model and chose loft feature for construction. For loft practice I began construct 1/4 of model using loft feature (with rails).

 

When I chose objects "Start point", "Section 1", "Section 2", "Section 3", "End point" as cross sections and "Rail 1", "Rail 2" as rails I got error.

What is wrong with this?

 

when I chose objects "Start point", "Section 1", "Section 2" as cross sections and "Rail 1", "Rail 2" as rails I got part of 1/4 model.

 

I spent a lot of time and have no result.

 

May be using loft feature is wrong way?

Any suggestions? Thanks for reading.

 

I am using Autodesk Inventor 2013 x64. Attached file Loft56789.ipt

I have moved your thread to the Autodesk Inventor Forum.

I didn't take the time to try to diagnose the problem - but,

I am easily able to make a second loft, then simply Stitch the 2 Lofts together.

(in image - I often pick my Rails first, then the Sections profiles)

 

 

About to pick the End Point.

You might try reversing what you define as sections and rails. That is, use your rails as sections and a section as a rail. This would avoid the the potential degenerative condition of lofting to a point.
