Hi Lanren, so here's what I was talking about - trim this surface here:



Click the "Isocurve" option in Trim and use this isocurve as the cutting line:



Then remove this part of the surface here:



Repeat that around all the other pieces:



Now you can select these edges and do a Blend:




I think though that you'll probably get better results using filleting instead, rather than a "patch by patch" method like you're currently trying to do. See the posts above for some descriptions of how to use filleting, you instead build a full shape instead of little separate surfaces, but with sharp corners, then use filleting to round out those corners.

If you want to only work in a patch by patch method like you're trying to do, you may have better success with that particular method if you use Rhino instead since Rhino's Network command has options for continuity in it which MoI's does not currently have. If you need to use those options then use Rhino for doing your model instead of MoI.
