I am trying to create a variable radius fillet between 2 faces. NX face blend gives me error as "Radius of Curvature on face is smaller than input radius". I checked minimum radius of both faces using Analysis -> Minimum radius and both faces minimum radius is greater than all values keyed in for varaible radius. For ex:
For face1 Minimum radius is 0.6
For face2 Minimum radius is 0.8
Values given in variable radius is 0.3, 0.2, 0.1 at different location. I plotted a cubic curve with given data and plot was having all radius values less than minimum radius values.
Following things were tried and everytime got same error message:
1) Rolling Ball -> Circular -> Radius location at different point on spine curve
2) Rolling Ball -> Asymetric Conic -> offset1 and offset2 are defined as distance at different locations on spine curve. -> rho is automatic ellipse
What could be going wrong and how we can have check about which radius values will work face blend.
