what I learned during ICT class

We already done with the Photoshop and InDesign thingy ma jiggy since last last week so now we actually to start using the program that call the Google Sketch Up. We are actually building a restaurant which this based on alot of math like the windows nearly alway be 4 feet, up is 3 and 2 the down. I will be honest one thing that...I just know that this sign " mean inch and this ' mean foot, I remember that I once learn about Sketch up in Grade 7 and I am really bad at it. I mean it been 2 years later and I just know that those signs are actually have meaning and different. Well shame on me...
