Thank you sooooooo much ... I knew it was probable something stupid easy ... wow don't I just feel like a noob LOL

Hey all,

First post .. and I'm sure it's a stupid noob question .. but I looked and couldn't find an answer.

I'm trying to model an aquarium sump that I have at home. I have all the measurements. It's basically an open top box with baffles, etc. inside. now when I model the outside edges of the box it adds a top to it automatically that I can't (or just don't know how to ) delete. How can I stop it from doing this?

And I love the program so far (2 hours) and thanks for the help.
