NX 10 - surface rather than face selection for child features

[longroadtrip]

is there a way to make a child feature (say and intersect line between two surfaces) to always look at the entire surface rather than just the faces that are selected at the time of making it.

as the design is changing, and the surface changes, i am having to rebuild every thing because the child features are losing the faces that they are built off, even though the surface is still there, and i have to re select all the faces.

thanks

This is exactly why NX has so called selection rules, Instead of selecting a single specific face which happens to be 100% correct at this moment in time,
you should use "smarter" selections which will work even when the geometry changes. I.e Tangent Faces/Adjacent faces/Feature Faces/Body Faces/ region faces etc.
The selection rule in use per selection step is saved in the feature and updates if/when the geometry changes.

If you have an existing feature which uses , say "single face" on "Intersection curve set 1", you can right click ON the selected face and change to a different selection rule.
