This is really kind of you Rudy, Thanks. I've got to say i've been doing this all wrong. My door way was built using a capsule (as shown in picture). After i adjusted the opening I then selected the rectangle selection tool and made my cut off point in the middle and deleted them. The base become a great clean cut. Yes I know Rochr has it completely different and I also know that mine will become a problem later on when grouping or something like that.....hence Rudy does it the right way, but, it just seemed to work for me at this time of my modeling career in C4D. LOL.
Smile, your dead a long time :)
