Hi Mike, I'm really glad that you're enjoying MoI so much! :)

Thanks for your feedback, and just a couple of notes on a couple of things:

Check out the Rebuild command for something like this for simplifying a curve:
http://moi3d.com/2.0/docs/moi_command_reference10.htm#rebuild

It basically reconstructs a curve by sampling points from it and building a new curve through those sampled points, and you can control some parameters for how many sampled points are used, and the method for the resampling (whether to use a fixed number of points or to use as many points as needed to achieve a particular distance tolerance between the new curve and the old one).

It does sound like you want to use the Blend tool to get what you want here, but you need to extrude the smaller circle above out to a surface so you will have 2 edges to blend between.

Also you want to do the extrusion with end caps turned off so that the edges you are blending between are open edges.

So that would look something like this - here's a curved surface with a smaller circle above it:




Extrude the smaller circle upwards to make another surface:



It's also a good idea to either delete or hide the small circle curve at this point so that it does not get in your way for the next step, because you then want to select the surface edge, which is in exactly the same position as the generator circle, and you won't be able to target it when the original circle curve is sitting there.

So then select these 2 edges:



Then you can use Construct > Blend to create a blend surface between those edges.




So basically to construct a surface blend you do that between a selection of 2 surface edges - it was probably not working for you before because you had a selection of 1 surface edge and 1 curve object instead of 2 edges.
