Face Blend creation using law curve

Experimenter
Experimenter

I have been trying to create a variable radius fillet using face blend law curve. In law curve, we choose, cubic spline along spine. Spine given as input is closed curve. After that defined different radius values, at different parameters. NX gives error as "Invalid law function data". Is there any specific process to define radius for cubic spline fit along closed curve as apine.

In principal it should work. In attached image I used the edge as spline but also worked using the spline that created the inner law extension surface.

 

First check you can do fixed radius blends around the edge in the range of values you have.

Also check that you do not have two different radius values at the same point.

A large change in radius over a short distance could also be an issue.
