Fillet mechanism

Hi Burr,

Yeah variable radius means the fillet changes from one radius to another as it travels along the length of the fillet.

Like here is an example of a variable radius fillet between 2 planes, it starts at a large radius and then changes into a smaller radius:

I'm not really familiar with a style that moves the center of the fillet though, so I'm not sure what that is called. Do you have a link to the video?

I guess it must be something other than a circular arc fillet, because you can't really move the center of an arc and still have it tangent to the surfaces...
