NX "Geometry Properties" function does not recognize a blend face.

When trying to select a blend face created with small radius by "Geometry Properties" function, it cannot be recognized/chosen.
The issue frequently happens if the blend radius is less than around 1mm.
In addition, without depending on the data, the issue happens in all Edge Blend or Face Blend that is created with small radius.

Trying to choose a blend face like below, but cannot recognize the blend at all. There is nothing in the list for all selectable object, too.

Solution

Work Around:
1. It's relatively easy to select when viewing the model from a direction close to perpendicular against the blend face normal like below.

or

2. Making use of wireframe representation ("Wireframe with Dim Edges" or "Static Wireframe") as the rendering style like below.  It's possible to choose the blend face from outside of the model.

The issue is fixed in NX1980.

Notes and References

The issue is reproduced in NX1899 or later.
