Hey, I'm somewhat new maya (2weeks), have done a few online tuts and such but still majorly getting a hang for the ins and outs of modeling. Have a good deal of autocad experience but it hasnt seemed to help as much as I had hoped.

So my question is this (I searched the forums but didnt see this, sorry if its been answered ad infinitum): I have a cube, then take a cylinder, stick it inside and do a boolean -> difference, the result is of course whats in the following pic.



That part works fine, how do you model it so that when you apply a smooth or a higher poly count to it that it doesnt close up. How would you differentiate between a smooth edge going into the cylinder and a harder 90 degree edge? Is this the proper way to model this?

Thanks in advance for any replies.
