Is MoI better at filetting polysurface edges than Rhino?

Hi all,

I am having problems with the filleting of polysurfaces in Rhino and I am wondering if MoI can help me.

I'm looking for the fastest way to round the outer edges of my designs.
Right now with Fillet edge in Rhino I have to manually correct all the different edges with the proper radius, and I would like a way to automatically apply the widest possible radius to all selected edges.

Here are 4 links to images to explain.

1. This is the kind of shape I work with (letter combinations). I import it from Illustrator

2. From that I extrude a solid, but I want it to have round edges.

3. This image shows where the problem is. Even if I correct each radius in the preview the result is pretty bad.

Please let me know if MoI can do a better job with this.

Thank you,
