Pleas remember that SketchUp models objects in REAL 3d, so you use squares, rectangles, circles, boxes etc... and then VIEW them in way that produces 'Axo' or 'Iso' views, which can then be used to make images...
Search the 'Plugins Index' [accessed from the Resources menu above] for my longstanding toolset 'Axo + Iso View'... This will make a 30/30 Iso view for you...
As others have said - please learn to attach images/files to your posts - you are likely to get a better response when other members don't have to go off elsewhere to view what is in essence a simple image that could have been integral to your post...
