Variable radius face blend and radius of Curvature Connection

Experimenter
Experimenter

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.

Without seeing the part in question, I would suspect the following:

 

1. The location of the spine curve you are using

2. The tolerance in use.

 

If you can provide a file with some additional information, I'm sure someone would be happy to review it.
