Lofting- Cannot use faces or regions with inner loops as profiles

Hi all, I've had good luck with lofting faces before, but I've never tried with circle objects like this. I am trying to make a center axle plate to hold this wheel skin. since the axle plate is offset from the edge of the wheel skin, I thought lofting would be the easiest way to gradually connect the outside of the plate and the inside of the sidewall. You can see the two cross lines in the 'Sketch SIDE WALL" that I want it to follow. I even tried splitting Part Two to see if two halves would work. At this point I feel I've over thought too much and am just clicking buttons to see what sticks. Any help is appreciated!

Looks like a wheel so should be circular… Using a revolve is going to be the easiest way (you will need to sketch the profile though.

Kinda hard to explain. but where the loft joins the center disc… you were asking it to create zero length geomtry which it showed as an error of self intersecting geometry. clear as mud, I know. if you make the sketch 3 just a bit taller than the center disc you will get the result on the right here.

Thank you guys! MDesign, I followed your advice, and it worked! that will be a good thing to remember in the future. Of course, I then ran into another issue because of the way I had the other parts designed. Before giving up I tried Eric's advice and re-designed it all using a revolve. I was able to have much more control on things. I now have a finished product that I 3D printed and works great. Thanks' again guys
That little overlapping geometry and zero length geometry trips sooo many up. It did me at first too. Revolve is mostly going to be preferred for stuff like you got. But it does give a different surface contour so in some cases a lift might be preferred
