Yeah, MoI could do that, but these particular curves would have to be re-worked a bit. Here is a video that shows what Steve was talking about with regard to the joined surfaces. Fixing those, would allow a fillet in alot of those areas. In the last part of the video, i also show where, when you have an edge/angle that disappears or creates an issue for the filleter, you can trim the surfaces back and use the blend tool to fill in the gap. If you needed to do this, then this would need to be a "pre-thought" modeling method, because it would require you to have your surfaces extended "past the boundries" where you have defined the junctures, then trim them back. It wont work going to "Just the boundry", like you see in the video. This is Michaels explanation that the surfaces need to be created "larger", then trimmed.



If you need an example of what that looks like, i can present one here. You excluded the surfaces that had the more complex junctions from this model..
