Lofting errors

I have been running into problems lofting what in my mind couldn't be simpler: lofting between two circular faces.

 

I making a friction fit adapter for a pump, to blow up inflatable toys, but am at a simple really early step.

I have a hollowed cylinder, wanting to loft the top face to a sketch with the next step diameter. (There is one further step after this that I have planned.

 

After the same error, I tried adding a centre rail between the centre point of the bottom sketch and the top sketch, and the same error still persisted.

 

Work process: set up variables for various diameters, made bottom sketch, extruded upwards the given height, then made an offset plane (Distance over which to transition diameters). On this plane, I added my next sketch, projected the centre point (and face circles), and drew my next step inner and outer circles. 

I then tried to loft between the two faces, I received the error 'the loft could not be created, try changing the inputs.

I then added a perpendicular sketch and made a center rail, connecting the origin/centre of the bottom sketch to that of the top sketch.  Adding this to the lofting attempt gave the same problem.

 

Lofting has been something that has been very hit or miss for me in the past, but I am unaware of why.

I'd appreciate any advice/direction you may have to give.

 

I am a DIY hobbyist, using fusion360 intermittently for the past 8 years with slowly increasing depth/extent of use, making objects either for CNC or 3d printing.  I have done a combination of online educational videos and self exploration/googling for most of my learning so far.

 

Thanks

Ben

Loft does not support "hollow" profiles.  You will have to do this in two steps - one with all the profiles, and another between the smaller profiles, with type set to "cut":

Perfect, thanks! 

This explains several of my past failures as well.
