Hi Mike, unfortunately it's quite a difficult problem I think...
The fundamental difference is that VCarve is able to approach it more as an accumulation of separate cutting passes, while in MoI you're trying to generate the end result with just a single construction pass...
Especially when you have branching structures it will be very difficult to try and replicate many stages of cuts in just a single surfacing construction.
It's also not going to work very well to try and make a single surface that tries to "turn on a dime" and fold back over itself like in this spot here:
For something like that you probably need to have some more separation into pieces there - stop the "main side walls" at around these spots here:
Then the corner area would be built separately, more as a cone-like surface for just the corner, sweep the top profile down along the red sides there to make a surface that collapses down to a single point for a pivot area like that. That will be how you'll be able to make things come down to a single sharp ridge line.
You'll probably have to be breaking it up into somewhat more pieces with some cone-like pivot areas to get it down to a single collapsed centerline like you want.
It's still going to be a rather difficult type of work though...
