Creating an array of  objects is an easy matter in SketchUp. We show you how in our SketchUp courses. 
First select the item you wish to copy, in this case a component of the BMW Series 7. Then select the Move tool (or hit M on your keyboard) and start moving the item in the required direction. As you do so press down on the Control button on your keyboard (or Option on the Mac) – pressing Control as you move is the SketchUp shortcut for copying.
You can then punch in the required distance, eg. 4000 mm (4m). Then if you want 3 copies, type in x3 > and hit Enter. This results in an array of 4 BMWs at a set distance apart. If you then wanted a rectangular array you’d select the row of 4 cars and repeat the process either forwards or backwards.
To create what would be termed a Polar Array in Autocad select the item, then the Rotate tool instead of the Move tool. Rotate whilst press Control to copy around a point, punch in the angle instead of the distance, then the number or repeats.
Many useful tips and techniques can be found at the SketchUp website. And see many examples of our own clients’ work on our Facebook page.
