NX10.0 CAD: advanced blend settings: capping blend size at small surfaces

NX10.0 CAD: advanced blend settings: capping blend size at small surfaces

NX10.0 CAD: advanced blend settings: capping blend size at small surfaces

(OP)
Hello,

I have a ring with various grooves cut on the outside.
To simulate buffing of the outside, I want to put blends on the outside edges to dull the corners.
The objects is driven by expressions which can increase the width and diameter (and number of grooves) of the ring.
In the edge blend feature I use the "Outer edges Of Face" selection filter on a previous feature to select the required edges
This makes it that the correct edges are selected regardless of the size.


The problem lies with the small faces.
Everything is good when I choose a small blend radius (like 0,08 in this example).
But when I choose a greater one (such as 0,1), the blend feature fails because the blends intersect on the small faces.

Is there a way to have edge blend limit its blend on edges that would intersect otherwise?
Or prehaps ignore those edges instead of throwing an error and refusing?

Kind regards,
Jeroen Duré

It's refusing because you're effectively "modeling away" the top face when you increase your radius value AND when you choose all 3 edges at once. You would have to apply a blend to where all 3 blend edges intersect each other at the exact same point for this to effectively work the way you want - decrease your radius value if you must use equal radii on all 3 edges.
