Dear Friends,

When I use edge blend command I have to select all edges one by one of same feature even I had already toggled on the option "Blend All Instances".

What version of NX are you using?

Th Blend all instances is used when you have created an array of features and then apply a blend to one of them, it get applied to them all.

Check your selection intent options and use tangent curves or all in face.

I am using nx4.

what u said is OK, but suppose if I created a rectangular feature and I want to give blend on all four edges with a single edge selection then what should I do?

Use body edges from the selection intent
