Inventor Lofting Issue

"modeling failure in asm. "
"Modeling failure while creating edges resulting from face-face intersection"

I am trying to loft a web for a part. I have sketches running the length of the open area, all my geometry seems to be correct, to the best of my knowledge.
Do i HAVE to specify a center point for the loft or will rail type construction suffice?

Thank you in advance.

Cheers!

Why not attach the ipt file here?
Without the sketches it is not possible to tell what you are trying to loft. From just the dwf it looks like a Rib would work.

I tried to post the ipt but augi wanted a dwf.

Oh.... duh and doh, i just zipped the file. silly me =D

I noticed your Sketch1 was not constrained relative to the origin.
I would recommend starting with this document -

I remodeled the part using a simplified techique.
Now that I understand the geometry I would go back a second time and start over, but if you look at my feature history you will see it is much more simple (not counting finishing fillets). (Click on thumbnail for larger image.)
Are you working from a drawing that you can share for the dimensions?
