Hi Peter, I'm not quite sure what result you're looking for, but here are some steps.

First there is this outer ring of curve objects:



Those are the ones that you need to delete or hide before being able to select edges.

Then select a pair of edges like this:



And run Construct / Blend to make a smooth surface between them:




MoI's blend is currently limited to only being able to perform a blend between 2 edges at a time. Currently if you want to do it between 2 things that have a different edge setup like if one is broken into pieces, then you need to select the longer edge, and break it into similar pieces using Trim with "Add trim points" to place a break point to cut up the edge.
