How to select the whole surface of an hole?

[ptc-3978980]

Hi all,

i am new to Creo 2.0, i started studying Creo few weeks ago under the guide of a trainer. But i will not be able to ask him for my problem until the end of the Christmas holydays, then i hope to find an answere here.

Before going on, i apologize for my bad english.

Looking a the problem, i have two holes different whose axis are perpendicular and intersecting and the diameter of one is bigger then the other.

I added a chamfer on the edge resulting from the intersection of this two cilindrical surfaces, and now i would like to add a full round as well so that the chamfer surface resulting will disappear.

But i can't select the whole cilindrical surfaces for each one of them, Creo let me select just half part, preventing me from obtaining what i want to. In fact, by selecting only half side for each surface, full round keeps the chamfers in the side where i could not select the surfaces.

I tried using extrusion as well as hole features, getting the same behavior. Is there a way to achieve what i want to?

But most important, was i clear enough? I am afraid to not explain myself very well due to my bad english.

Thanks for taking my problem in consideration.

Giuseppe.

Welcome to the forum. Tangent surfaces are automatically selected so you only need to select one surface of a tangent surface chain. In other words, you just need to pick an inside surface of one hole and the inside surface of the other hole (both highlighted in blue in the picture) as long as they border the surface that is to be removed, then click the "full round" button. It should automatically select the chamfer surfaces as the driving surfaces to be deleted. See below:

Yes thank you for clarifying me this aspect Eric.

Now everytime i will see highlighted only half part of a surface whereas i should see it fully highlighted, i will not care longer.

And yet, i don't know how i got half fillet before, it must be the fortune of the beginner!
