Hi Michael,

I think that it's inappropriate to keep the radius distance between each calling the Fillet command (and maybe Chamfer, Offset, Shell... too).
For instance, I select some solid and fillet its edges with r = 2. Then I select something else and want to fillet with r = 0.5. ...whoops... MoI uselessly performs a computation (or even freezes with complex shapes) for last input, i.e. r = 2, before I'm able to change the radius to r = 0.5. (Note that the exactly value of r is not critical, it is only for the illustration).
I suggest,
(1) not performing a computation until the 'done' button is clicked or
(2) adding a 'preview' button or
(3) not retaining last input or
(4) ...



Thanks
Petr
