Can someone suggest a methodology for creatings loft using 2d sketch profiles and 3d sketch rails? I'm having a hard time getting the rails to intersect the the profiles, avoid self-intersection errors, and getting the contours I'm looking for and was hoping someone could walk me through how they'd go about the process. As background, I'm fairly new to Inventor but have used Pro/Engineer for a few years.
I've attached a few images of (the key portion of) the part I'm trying to model. Thanks for the help!

You will most likely need to attach your ipt file of what you have attempted so far to get help.
