Loft between circles to create a reducing elbow

Hello! I am trying to create a model of a reducing elbow (4 to 3). I have the straight ends of the elbow and I was hoping I could loft between the parts.  I followed the instructions per the PTC help, but when I try to create Matchlines, I get an error that says "The profile must be closed." So I can only assume that I am picking the wrong vertex? I cannot attach the pkg file I am working with, but I can send it to someone that thinks they can help. Can someone please help me? Maybe lofting is not the way to go, but it was the only method that I thought made sense! Thanks!

Lofting would be correct. Can you attach a picture of the workplanes or send the pkg file?  2D profiles on each workplane must be closed and have the same number of vertexes.

If I understood your issue correctly, this is what you wanted to do.

Yes, that is pretty much what I want to do.  Is that in parametric? what commands did you used? I am in E/DM, some of the modeling commands are similar. Below is what I am trying to make. It is an off the shelf part that I can't find a model of anywhere.

This board is specifically for Creo Parametric.

I will move this question to Creo Elements Direct board so you can get the right help.

Okay, with your help I was able to kind of do what I wanted. I lofted 1 edge, but it wouldn't let me select both edges on part to part. I just did the outside edge to get the outer profile, then I did a sweep remove to shell the inside. This will work for now, I just wanted something closer to the real thing than what I had! Thanks so much for your help!
