How do I round this edge without other edges dissapearing?

[AS_11004841]

Im trying to round the inner bottom edges of this tank. It has this small pipe leading out. When I apply round to it. It opens on either side of my pipe. How do I not have this? It doesnt show the holes in the preview but when I click accept it does. Im on creo 10.

This seems to be a classic example of how the order of features can make things difficult. If it were me, I would put the rounds on the bottom edges, and then put in the hole feature, not the other way around. Kind of a case of modeling things the way you would actually build them.

Hi,

if it is possible then upload your model.

The method of @KenFarley will probably work. Enclosed is a Creo 7 model with an alternate method to achieve this in part mode using multi-body.
