I have some confusion over the relationship between the Minimum radius of curvature vs. the potential values for thicken, shell, and offset. My understanding is that if the thicken distance is greater than the minimum radius of curvature, the thicken will fail.

I've attached a simple model of a pan with 10 mm corner fillets. It would be great if some could explain to me this relationship in simple terms. When I checked, it did say the minimum radius was 10 mm. The current shell has a thickness of1 mm. When I tried a thickness over 10 mm, it failed. I guess my main confusion is why this is called a "* Minimum* Radius of Curvature," and not a "

*radius of curvature." Any help is much appreciated! Thanks!*

**MAXIMUM**

Minimum radius = radius after the shell..... so 10mm (external) - 1mm (thickness) = 9mm (internal R.)

But 10mm - 10mm (thickness) = 0 (zero radius face left)
