|Sometimes a picture is better then words. The real reason is for those of you that like to build are dream, the program I used to draw the pictures is call Googlesketchup and its free. I use it for anything from small projects to the plain I drew for my house build. You can do 3-D the first time you try it out. It would take 3 months of college classes before they would probably even start talking about 3-D. I'm not up on whats allow to be posted in here but just wanted to share.

I could go on but all I can tell you is you want be disappointed.
