Hi Micheal,

This would be a great feature.
I would like to offer a suggested UI for the surface to surface.

1) Select the surfaces you wish to fillet that do not touch. If they touch then use the edge technique you explained above.

2) The command would allow you to determine how many radii change points you need. 2 points would be the default. Point A is the start and point B is the end of the fillet.

3) For every radii point created there are 2 input fields:
a. Radius: Define the Radius of fillet at this point
b. Percentage: Define the percentage of distance past point A where you want the fillet radius to change size.

Also allow for a 0 radius value.

Thanks
