    Isn't that how it was supposed to look?

    Presumably the diameters of the circles are meant to be somewhat random, as that was my impression from your original linework.
    If they are meant to be the same diameters, that would be easy to do.

    given you're dealing with circles (closed) one could simply draw ruled surfaces (command: rulesurf) to draw the meshes automatically between each circle?

    Surftab command will let you experiment with the number of surface tabulations before using the rulesurf command.

    Loft could also work but would almost be too complicated in my opinion.

    If you use Rulesurf you're going to end up with a series of straight cylinders, not a single organic shape like what is shown in Dadgad's images.

    In the image below, I used Rulesurf for the object on the left and Loft for the object on the right. Not only was Loft easier and faster than Rulesurf, but it is smooth and organic in appearance and it's all one solid piece as opposed to the linear and faceted shape of the Rulesurf object which is made up of 3 separate hollow pieces.

    For my money, Loft is the way to go.

    Additionally, once created you can still affect the overall shape by changing the surface treatment of the completed lofted object, as I mentioned previously.

    The process is cumbersome but a more seamless surface can be had via Control Vertex modeling of a nurbs surface. SurfSculpt to make it a 3D solid.

    That looks really good SEANT, I figured there would be another more modern way to do it, my techniques on such things tend to be pretty old school.

    Seant, that's really cool. Would you be able to explain a little more in detail how you did that? I'm totally new to things like "Control Vertex modeling of a nurbs surface" and "SurfSculpt".
    It's deja vu, all over again.

    Here's a quick screencast demonstrating the general procedure for processing a revolved surface to allow for vertex editing. Part of the problem regarding manipulation is the selection methods have to coordinate Object selection, to highlight the Vertices, then a vertex filter, to grab the group of vertices for any particular operation.

    The right click menu whilst vertex editing allows for Move, Rotate, Scale, and Stretch (same as move).

    Once the surface shape was as needed, a "Planar Surface" can be created (aligned with the World XZ plane in my example) and used to cap the curvy surface via the SurfSculp command.

    Surftab was an example given the ring pic above that I assumed was what you were trying to model (my bad). BUT there are other mesh commands that can draw the mesh thru multiple closed objects that would be able to emulate your desired result at the very least and would be easier yet than loft in my humble opinion...

    If you have an actual model or 3d example of what you are trying to draw in Autocad you can always use Recap 360 to take multiple photos of the object which will be able to create a complete 3d model of the object which basically gets emailed to you after it is processed by Autodesk.

    OR, and I'm just using this as an example, if you wanted you could model it from clay, then use this feature to create a complete 3d model of the object that would get emailed to you as a DWG file.
    It's possible is all I'm saying...
